Math Problem help??? stupid babysitting! (6th grade word problem math)?

1.Gerhart bought a 3.95 bagel, a 1.45 dish of rice pudding, and a 1.10 cup of coffee for lunch. He left 1.30 tip. the tip was what percent of the cost of gerhart's food?

the food cost 6.50

1.30= what percent of 6.50

1.3/6.5= what percent

1/5=what percent

.2 = what percent

20%

-----------------------------------------

2.Winona and Tom went to dinner and left a 6.48 tip, which was exactly 18 percent of the total bill. how much was the bill?

6.48=.18 B

6.48/.18=B

36=B

$36

Inez bought a 5.95 ceaser salad and a 2.45 bowl of soup for lunch. she left a 20 percent tip of the food total on the table. the final bill included a 5 percent sales tax on the food total. how much did inez spend on lunch?

5.95+2.45=8.40

20% 0f this is 1.68

5% of this is .42

add them get $10.50

1. So Gerhart pays 3.95, 1.45, and 1.10, for a total of 6.50. To find the percentage that the tip is, you divide the tip by the cost of the food. 1.30/6.50 =.2, or 20%.

2. If the tip is 18% of the bill, that means that 6.48/X(the total bill) = .18 If you cross multiply, you get that 6.48/.18 = X, so X, the total bill, is 36 dollars.

3. 5.95 + 2.45 = 8.40 for the food. 20 % of the food is 1.68, so now the total is 10.08 for the food and the tip. The sales tax = 8.4 times .05, which equals .42. Therefore, the total that she pays is 10.08+.42=10.50.

Hope this helps!

Dear Rosa, Both the answers (67 cups) appears to be correct but is not! Suppose you made 100 cups of lemonade and could sell only 67 cups, you get $10 profit for the 67 cups but you are stuck with 33 cups that may go waste and so you need to deduct 3 dollars and 30 cents from the $10 that they made! So, real life problems are far more difficult. But for the purpose of teaching you addition, subtraction, division etc. it is OK.

1. The tip was worth 20% of Geharts food

2.

3. He spent £10.50 on his lunch

Hope my answers helped you alot, Sorry I could not answer question 2. I'm only 13 therefore it was a little hard.

1) 3.95 + 1.45 + 1.10 = 6.50

1.30/6.50 = 0.2 = 20%

2) 6.48/.18 = 36.00

3) 5.95 + 2.45 = 8.40

8.40*.20 = 1.68

8.40*.05 = 0.42

8.40 + 1.68 + 0.42 = 10.50

1) add up the food cost. Then divide the tip by the food cost. In your answer move the decimal two places to the right to get a percentage.

1. 1.30/(3.95+1.45+1.10) = X (20%)

2. 6.48/.18 = X ($36)

3. ((5.95+2.45)*1.20)+((5.95+2.45)*.05) = X ($10.50)

GOOOD
