15.79

Step-by-step explanation:

To find the average amount of monthly weight gain, we need to find the average first.

Average is defined as the sum of the values (in our case value of weight in each month) and that sum divided by the number of values (in our case it is the number of months).

Finding the average:

Since there are 13 values so we sum up all the values and divided by the number of values.

When rounded to the nearest hundredth of a pound we get 15.79 pounds.
