A) 6 pounds per month
B) 13 pounds per month
C) 19 pounds per month
D) 36 pounds per month

Answer 1

A. You can add 6 times in 12 but before that,you have to add 160+6 12 times

Answer 2

6 pounds per month

Explanation:

Given :He initially weighs 160 pounds and by the end of 12 months weighs 232 pounds.

To Find : What is the approximate rate of change in Anthony's body weight?

Solution :

Initial weight = 160 pounds

Weight after 12 months = 232 pounds

So, difference in weights = 232 - 160 = 72 pounds

So, change in weight per month =
`(72)/(12) =6`

Hence the approximate rate of change in Anthony's body weight is 6 pounds per month
