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.
