Question

Jarrett’s puppy weighed 3 3/4 ounce of ounces at birth. At one week old, the puppy Weighed 5 1/8 ounces. At two weeks old, the puppy weighed 6 1/2 ounces. If the weight gain continues in this pattern, how much will the puppy weigh at three weeks old?

Answer 1

Explanation:

First week increase:

5 1/8 - 3 3/4

= 41/8 - 15/4

= 41/8 - 30/8

= 11/8 ounces

Second week increase:

6 1/2 - 5 1/8

= 13/2 - 41/8

= 52/8 - 41/8

= 11/8

Third week weight:

52/8 + 11/8

= 63/8

= 7 7/8 ounces
