Question

One dozen eggs cost $1.98. If the charge at the register for only eggs, without tax, was $11.88, how many dozen were purchased? Round answer to the nearest cent.

Answer 1

They purchased 6 dozen eggs

Explanation:

The total cost is the cost per dozen times the number of dozen purchased

total cost = 1.98 * n where n is the number of dozen

11.88 = 1.98n

Divide each side by 1.98

11.88/1.98 = 1.98/1.98 * n

6=n

They purchased 6 dozen eggs
