Trust Ray!   Apples cost 15 cents and Oranges cost 10.  Just write the two equations and it is clear.

haha good question :]\nwe're just studied those in math, and a lot of our problems had "real-life" situations, so i'll just give you some examples of them.\n"A farmer has at most 80 acres for which to plant two crops, corn and wheat. Planting and harvesting cots, for which no more than a total of $12,000 is available, are $300/acre for corn and $100/acre for wheat. How many acres of each crop would you suggest he plant?"\n"Ken is planning a picnic for the youth orchestra. He is going to make chicken sandwiches and egg salad sandwiches. He will make no more than 20 sandwiches, because many people may bring their own. He figures that the number of chicken sandwiches should be at least twice as many as the number of egg salad sandwiches. Ken says that there is only enough chicken for 16 chicken sandwiches. He says that there should be at least 2 egg sandwiches..."\nI think these could be times in which you could use a system of inequalities. I guess if you had time to calculate it all...\n<333

Can you use money? I would say that John has $31 and he plans on dividing it equally between his four kids so they can buy themselves a treat.  How much money would each kid receive?  The answer would be $7.75.

1. 3 of you went with $ 10 each , so you have 10*3 = $ 30.\n2. There is a bill for $ 30 with $ 5 discount, so you have to pay $ 25.\n3. You can not devide 5 in 3 pars so you give away $ 2 at tip.\n4. The amount spent mounts to $ 25 +$ 2 = $ 27.\n5. You are left with $ 3, which you devided in 3 parts. So, all of you have $ 1 each.\n\nNow, if you see the question in perspective of one of the 3 people. The addtional $ 2 are spent in giving away the other 2 frineds their share of $ 3 left. \nSo, in this case the dollar left is with you.\n\nEnjoy the dollar.

24 is the first number divisible by both 6 and 8 (forget mathematical term sorry).  6 going in 4 times and 8 3 times. So he bought 4bags of apples and 3bags of oranges.

if 6 is $2  then each 1 must be 1/3 of a dollar.\n\ntherefore,\n\n40 x 1/3 =  amount of 40\n\n40/3 dollars or $13.33333333333 (rounded to $13.33)

Actually I had something to help you but x=0 which makes it pretty difficult.\n\nI guess you could try to talk about tomatoes or something.  Say Tom (X) has 1/2 the amount of tomatoes that Jill has, plus four.  Or in other words, if you take Jill's amount of tomatoes, multiply it by two, and take Tom's amount and multiply it by three, there total amount of tomatoes will equal 12.  How many tomatoes does Jill have?  How many does Tom have?

The waitress calculation is wrong...\n\nYou me and Sally gave the waitress $10 each for a total of $30.\n\nThe waitress gave back $5\n\nWe gave the waitress back $2.\n\nTherefore, the waitress has $30 - $5 + $2 = $27

nothing...the person who wrote that just took the wrong approach to finding the answer.  the math was just done wrong...\n\n10x3=30 each guy pays 10\n30-3=27 each guy get back one dollar\n27-2=25 the bellman pockets two\nthere are $25 left\n\nin the problem when the counter man keeps two they add it rather than subtract it like they should have

i assume you want a demonstration of the use of numbers and math in daily life... try these\n\n1. suppose brand a of candy sells for 2.37 for an 8 oz bag and brand b sells for 3.05 for a 11 oz bag ask audience which is a better deal ?, why ?, how can we compare the 2 brands to get a definite answer ? Now you introduce the idea of unit price which is $amount/weight do this for each brand. The smaller value for the two brands is the better unit price or the better deal.\n\nfind three different size circles. measure for each one the distance around the circle and the distance across the center of it write these values down for each circle.  Now for each pair of measurements divide the around value by the across value. ask the audience to compare the three quotients and note anything unusual.  what will happen is that no matter the size of the circle distance around/distance across is the same value about 3.14159. now state that pi is the ratio of dist. around / dist. across for a circle and is the same regardless of size of circle

Items that cost a total of $10.00:\n\nGranola bars - 2.79\nWater - 2.58\nFrozen meal - 2.34\nTomatoes - 2.29\n\nHow I did it: I simply mixed and matched until I found the items.\n\nItems that cost a total of $25.00:\n\nmeat 3.99lb; granola bars 2.79; oj 1.36; eggs .79; bread 1.89; cheese 2.06; butter 1.39; oatmeal 1.19; water 2.58; frozen meal 2.34; yougurt 2.39; tomatoes 2.29\n\nHow I did it: This time, I worked backwards.  I added the prices of all the items and the total was $35.53.  Therefore, I looked for a set of items that cost $10.53.  When I found those items, I EXCLUDED those from the original list and kept the rest (since $35.53 - $10.53 = $25.00).

Percent of increse-Sally was walking down to the toy store.  A man that worked at the toy store was her frind's dad.  A week befor last week sally saw a doll that shee wanted to buy.  It was 10.00 dollars.  Sally brought 20.00 with her to buy the  doll.  Ohh no! when Sally looked at the doll this week it was 15.00 dollars! Sallys mom had told her that she could but the doll if it was cheaper or if it only got a 9%increase. Sally remeberd those horrid words. She pulled out a sheet of paper ond wrote:.............the origanal price was $10 and now it is $15.\nS: The percent of increase of the doll I want to buy..................\nO:Doll  $10 Now it is $15  \nL:I will multiply and subtract and divide. \nV: $15-$10=5 5/15 * x/100  x*15 = 5*100   x*15=500 divide both sides by 15. x= 33 1/3   \n\n\n\nI can buy the doll yeah\n\n \nE

How many ways to pick 5 from 20 if order isn't important?\nAnd, how many ways to pick 2 from 7 if order isn't important?\n\nFor the second question, you have... 1,2 1,3...1,7 or 6 that include 1. Then 2,3 2,4... 2,7 which is 5 more. Then 3,4 3,5...3,7 which is 4 more. Keep doing this and you will see the answer is 6+5+4+3+2+1 = 21\n\nFor the first part 5 out of 20, note that the total number of arrangements of 20 things is 20! which is 20 x 19 x 18 x17 ..... x 2 x 1. But for every arrangement that you take the first 5 of, there will be 15! ways to arrange the rest.\nAnd for those first 5, you can get them in any order which means that 1 2 4 3 5 is the same for you as 2 3 1 4 5. So, you need to divide the 20! by both 15! and 5! which looks like this-  20!/(15! x 5!) and equals 15,504.\n\nNow for each pick from the cable houses (15,504 possible) you have 21 different ways to pick a no cable set. Therefore, multiply 15,504 by 21 to get your final answer. 325,584

In case you want more than just the answer so you can do similar problems on your next test:\n\nQ: What do have to find? \nA: The number of bottles of apple juice (call it A)\nand the number of bottles of orange juice (call it B).\n\nQ: What do you already know about A and B?\nA: You know that together A and B total 12 bottles.\n(A + B = 12)\n\nYou also that you paid $15 for the 12 bottles. You paid $1 for each bottle of apple juice (1xA) and you paid $1.50 for each bottle of orange juice (1.5B)\n\nSo $15 = $1xA + 1.5xB\n\nQ: What next?\n\nA: You have two equations with two unknowns:\n\nA + 1.5 B = 15\nA +     B = 12\n\nSubtract the left hand sides and the right hand sides to get\n      .5B = 3\n\nDivide both sides by .5 to get\n    B = 6\nso  A = 12-6 = 6\nCheck:\n$1x6 + $1.5x6 = $6 + $9 = $15
