I did it this way:\n\nI know that 8% of the tota bill is $4.00\nI'm looking for the 100% of the bill... which I'll be naming "X".\nThen, I used the rule of 3:\n\nX   --------   100%\n4.00  -----      8%\n\nX = (4*100)/8\nX = (400)/8\nX = 50\n\nSo... the bill was $50.00\nPlus, the $4.00 tip... The total bill was $54.00\n\nBe sure to say Hi to your math teacher from me!

You have to bear in mind that the drinks were not actually $27 dollars, it was $25.  Just because you gave them a dollar each back, they ASSUMED it was $27.\nEven though they had paid $27, you still had to pay their bill of $25 which would leave you the $2.....\nthe missing $1, is therefore, not a missing dollar....!

Well I have two jobs and one is waiting tables at a tiny place here in my town. There is ALLOT to the to-go orders. I answer the phone, write it down and I make sure it is correct for the customer and then I take it to the cook. She cooks it and I bag it up and make sure all of the necessary items like salsa, sourcream etc......are inside and of course I ring up the food. (it takes time). So i would say tip the person 25 cents if it is 3.00 or more etc...it is only fair. We work hard to get you happy with your order so a tip bit of money wouldn't hurt.

The cost of 7 hamburgers and 3 slices of pizza would be\n20 - 1 = $19\nThe cost of 8 burgers and 2 slices of pizza would be\n20 - 0.5 = $19.50\nLet x = cost of a burger and y = cost of a slice of pizza\nThe first statement implies\n7x + 3y = 19\nThe second statement implies\n8x + 2y = 19.50\nNow solve these two equations either using substitution of elimination.\nAfter you solve for x and y, you will see that\nx = 2.05 for one burger and y = 1.55 for one slice of pizza\nThus, the cost of 5 burgers and 3 slices would be\n5(2.05) + 3(1.55) = $14.90\nYou paid with a $20, so the change would be\n20 - 14.90 = $5.10

The error is in the way the question is stated at the part where you say each man paid $9 for the room.  They didn't.  They paid $8.33 each, but don't know it.  They each paid $.66 in a tip they also don't know about.  That times 3 = 27 and with the $3 of refund = $30.00.

It is a matter of wording.\n\nThe bill was $75.  The cashier gave them $5 discount, so now the bill is just $70.  So the waiter gives back $1 each, so everybody paid $24, giving us $72.  $70 of which went to the cashier, and $2 into the waiters pocket!

The mistake is adding the $2 to the 27.  You should subtract it to result in the $25 total of the bill.  That's what they should have paid, but they paid 27 because the bellhop kept the extra 2.

this is dumb... where did the $9 come from?  Something cost $25 so there was $5 change.  Dad took $2 and so that leaves $3.  Which is $1 for each kid.

the trick to this question was in the wording and how the math was worked out in error\nthe  $3 they got back is what needs to be added to $72... NOT the $2 the waiter kept \nsince they got that back that is what you add... since the waiter kept $2, it is already included in what they paid

1) x spent on rest, x + 600 on food, x+x+600 = total spent\ntotal salary = 5/3 * spent = 5/3*(x+x+600)\n\n5/8*(x+x+600) = x+600\n375-600 = -1/4(x)\n900 = x (on rest)\n1500 (on food)\nspent total of 2400\ntotal salary = 4000\nsaved = 2/5 of total = 1600\n\n2) if it took 20 minutes (from 10:15 to 10:35) to change 50 degrees (20*2.5 = 50)\nand it took 30 minutes to change back 37.5 degrees (50-12.5=37.5) \n\nThen, the rate of cooling is 37.5 degrees/30 minutes = 1.25 degrees / minute of cooling\n\nTherefore, it took ten minutes of cooling to change 12.5 degrees, which means the time at which it was 12.5 degrees hotter than 11:05 was 10:55 pm.\n\nP.S. you have one tough teacher!  glad to see that you are getting a good education, cause these are not easy questions.

No servers should have been tipped right in the first place by the customers or the restaraunt should calculate it in the check. As an ex server I felt more like a begger than an employee at a restaraunt cause customers know they don't have to tip.  2.13 an hour is stupid.

Break the problem down into parts.\n\n1/3 of the 75 guests do not eat meat. That means 25 don't eat meat and 50 do.\n\n30% of the 50 don't eat spare ribs. So, 15 don't eat the ribs and 35 do.\n\nEach person that eats ribs eats 0.3 kg. With 35 people, the ribs that were eaten would be: 35(0.3) = 10.5 kg.\n\nTo get that many kilograms (without going over too much), Edna could buy:\nfour 3 kg packages (12 kg) --> $100\nthree 4 kg packages (12 kg) --> $90\ntwo 4 kg and one 3 kg (11 kg) --> $85\n\nTo save money, she should buy two 4 kg and one 3 kg, which costs $85.\n\nI solved it this way because it's easy to think through and check my work if I make a mistake.\n\nHope that helped.

I estimate the meal was $20.65     Suz estimated cost was closest to her actual cost.   This is what I came up with (approximate figures) Suz-actual $4.36 paid $3.52      Annie- actual $ 6.50 $ paid $7.50   Cynthia- actual $6.76 Paid $8.80.

All tips and service charges are not mandatory. At the restaurant I worked at it said on the bottom of the menu that 10% service charge would be added to the bill for tables of 6 or more, but you could ASK for the tip to be removed. Some of the waitresses grumbled a bit when asked to do so, but then found that the customers actually ended up tipping more than the 10%. Some people do not tip at all, perhaps because they have little money but that doesn't mean they did not enjoy the meal. Indeed they might recommend us to someone else instead which is worth much more than a tip. I would not have worked out, I would have asked for the service charge to be removed as this is within your rights. If it was compulsory they would just charge more for the food which would be less confusing. \nxx

All in all, the three guys spent 10 dollars (-10) and got a dollar back (+1), making their loss 9 dollars each (-9).  \nSo in total, their loss is: 3 * -9 = -27\n\nThe lodge gained 30 dollars, and gave back five dollars. (30-5 = 25).\n\nThe bellhop gained 2 dollars (+2).\n\nSo, if everything is balanced in terms of gains and losses, -27 + 25 + 2 = 0.  Thus, there is no "other dollar", that was just a trick (the purpose of the story problem).  The wording of the problem led me to think about it in an incorrect manner, initially... which is the point!\n\n--- edit ---\nHah, I opened this screen up to answer the question, then did some office work before typing the answer, and by the time I posted, someone had already put the correct answer, which I didn't realize when I posted... hah.

Sometimes you don't want to tip because the server gave you almost no service.Heres your seat ,what do you want to order,here it is and then put the check down.......What happend to may I get you something else..would you like your food  boxed. you know the service part...Then you see a post like this one.must be from the one who did not give you the service as it seems alittle short..IE.( get a job as a server making $2.13 per hour for 1 week and ask this question again.) ...........Tipping is by the service given..If you took that job "wait person" . So smile and give service like you would want given you.Then you'll get a TIP
