5 bags of apples cost 3.00 at the same rate what would be the cost of 7 pounds of apples?
361277
if a 5 pound bag of apples cost $3.00 they would be, .60 per pound 3.00 divided by 5 = .60  so to find out how much 7 pounds would cost multiply .60 x 7 = $4.20  if you are having difficulty with your math homework maybe you should ask your teacher for someone who could tutor you.  see, you may be taking a short cut by getting the answers to your math homework on here, but yahoo answers will not be sitting next to you while you are taking a test, and if you were my child i would rather you ask for help in learning how to do the problems and pass your tests than to just get your answers off the Internet for your homework, so now that i have explained how to get the answer to your math question... answer this one, at the same rate as above how much would you pay for 4 pounds of apples and how much would you pay for 9 pounds of apples.  e-mail me your answers. Good luck in your learning

1. Square everything in the first set of inequalities.\n\nIf 4 < sqrt(x) < 9, then 4^2 < [sqrt(x)]^2 < 9^2\n\nor, 16 < x < 81.\n\nAs a test, let's choose x = 64. I picked it because it has an easy square root.\n\nIf x = 64 (and note that 16 < 64 < 81), then sqrt(x) = 8, which is greater than 4 and less than 9.\n\n2. If the total cost of x apples is b cents, then the cost of 1 apple is b/x cents. x * b/x = b, which is indeed the cost of x apples according to the problem.\n\nIf 1 apple costs b/x cents, then y apples cost yb/x cents.\n\nAs a test, suppose that 5 apples cost 20 cents. (That is, x = 5, b = 20).  In this case, 1 apple costs 4 cents.\n\nHow much are 6 apples (Let's let y = 6). 6 apples would cost 24 cents.\n\nNow, what is yb/x?\n\n6*20/5 = 120/5 = 24.\n\nIn this case, it checks out. (It will for all cases, but one case doesn't actually prove that it works. It really only justifies it. But it is right :D)

So where's that starting point?  Either we start (yesterday) with Mary having $785.63 we subtract $57. and $125. for 603.63.  Then we add $57.25 for a total of 660.88 (B) \nOR\nwe start we $785.63 (today) anb subtract $57. and $125 for $603.63 (C).  The $57.25 doesn't matter cause Mary did that yesterday....

75 times 3 = 225 so its $225.00

The total of what? If you're wondering the cost of each type of onion per pound, here's how you do it:\n\nTotal $ spent: $7.08\nYellow onion: 4 pounds, each pound costs $X\nRed onion: 4 pounds, each pound costs $X + .05\nMake an equation - \nTotal money spent equals number of pounds of yellow times cost of yellow plus number of pounds of red times cost of red:\n7.08 = 4(X) + 4(X + 0.05)\nSolve:\n7.08 = 8X + 0.2\n8X = 6.88\nX = .86\nThe cost of red was $X, so red onions are $0.86 per pound.\nThe cost of yellow was $X + 0.05, so yellow onions are $0.91 per pound.\n\nDoes that help?

Depends on the size.\n\nTry putting 4 or 5 in a bag for $1.  But, I wouldn't make them too big.  People like to feel like they're getting a bargain.\n\nHave Fun!\n\nBest of Luck to YOU!

6.613 lbs .\nBecause average serving sizes of an apple is 300 gr.\n(300x10)/453.59237 =6.613lbs

You want to find x number of Kg worth $6.60 per Kg mixed with 10 Kg of nuts worth $8.50. So, you construct the equation $6.60x + $8.50(10) = $7.10 (10+x). This may seem confusing, but I'll try to make sense of it. There are $85 worth of nuts in the mix ($8.50 per Kg times 10 Kg) You want to add to that an x amount of Kg costing $6.60 per Kg. And you want the final mix to equal $7.10 per Kg. This made sense to me the most when I was learning these types of problems. YOU WANT THE TOTAL AMOUNT OF DOLLARS SPENT DIVIDED BY THE KG TO EQUAL $7.10. The left side of the equation I have given you is the cost in dollars of the mix, and the right side sets that equal to $7.10 dollars per Kg times total Kg of the nuts. Solve for x. You should get 28 Kg for x. Good Luck!

72 divided by 16 oz.that are in one pound= 4 pounds, there are 8 ounces left over, so 4lb. 8 oz, or 4.5 lbs

3 shirts x $18.99 each = $56.97\n$75 - $56.97 = $18.03 left over...\n\nIf we get more complicated, and include tax, it depends on where you live...  I'm going to use the example living in ny, since thats where i live...  I just looked it up its a 8.625% rate\n\nsoo..\n\nTake the $56.97 total x 8.625% = $4.9136625 sales tax\n$4.9136625 + the $56.97 = $61.8836625, which rounded off to nearest penny = $61.88 being the total price\n\nTake the original $75 - $61.88 = $13.12 left over...

Ummmmmmmmm... no, yours is a calculator error ;)  if you divide an apple into 3 parts you can put them back together... you just have a serious logic issue ;)

depends how big the apple is!!!

Let a be the number of apples\nLet (12 - a) be the number of oranges\n\nThen:\n25a + 18 (12 - a) = 251 cents\n\nNow multiply the 18 through the parentheses:\n25a + 216 - 18a = 251\n\nSubtract 216 from both sides:\n25a - 18a = 35\n\nSimplify:\n7a = 35\na = 35/7\na = 5\n\nOranges = 12 - a\n12 - 5 = 7\n\nSo Alice bought 5 apples and 7 oranges.\n\nAs a double-check:\n5 apples = 5 x 0.25 = $1.25\n7 apples = 7 x 0.18 = $1.26\nTotal = $2.51

OK - here goes:  \n\nLet X equal the number of pounds of the six buck coffee.\n\nThen, 6*X + 4*3 = 4.75*(X+3)\n\nSo, 6x + 12 = 4.75x + 14.25\n\nSubtract 4.75x from each side to get:\n\n1.25x + 12 = 14.25.\n\nSubtract 12 from each side to get:\n\n1.25x = 2.25.\n\nDivide each side by 1.25 to get:\n\nX = 1.8.\n\nTo check it:  1.8 pounds of 6 dollar coffee would cost $10.80.  3 pounds of 4 dollar coffee would cost $12.00.  Together, you have 4.8 pounds of coffee that cost $22.80, and $22.80/4.80 pounds = $4.75 per pound.\n\nSo, 1.8 pounds is the answer!

Basically: There is an initial $30 charge.  It should have been $25, so $5 must be returned and accounted for.  $3 is given to the 3 friends, $2 is kept by the manager - there you have the $5.  \n\nThe trick to this riddle is that the addition and subtraction are done at the wrong times to misdirect your thinking - and quite successfully for most.  Each of the 3 friends did indeed pay $9, not $10, and as far as the friends are concerned, they paid $27 for the night.  But we know that the clerk will tell us that they were charged only $25 and when you add the $3 returned with the $2 kept by the bellhop, you come up with $30.
