7. A caterer knows there is one broken egg in every 3 cartons. A carton contains 12 eggs. A caterer plans to serve 1200 eggs. What is the best estimate the number of cartons the caterer should buy?

9514 1404 393

  103

Step-by-step explanation:

For 1200 eggs, the caterer needs ...

  (1200 eggs)/(12 eggs/carton) = 100 cartons

of unbroken eggs.

The rate of broken eggs is 1 in 3×12 = 1 in 36, so the caterer must buy 36 eggs for each 35 unbroken eggs delivered.

Then the number of cartons that must be purchased is ...

  (100 cartons)(36/35) = 102 6/7 cartons

The caterer should buy 103 cartons of eggs.

i believe the answer is c.

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
