During 712 months of hibernation, a black bear experienced a weight loss of 64.4 pounds. On average, what was the bear's weight change per month? Round to the nearest tenth. Enter your answer in the box.

Total pounds of weight loss of bear in [tex]7 \frac{1}{2}[/tex] months = 64.4 pounds

We have to determine the bear's weight change per month.

We will use unitary method to solve this problem.

So, total pounds of weight loss in 1 month = [tex]64.4 \div 7 \frac{1}{2}[/tex]

= [tex]64.4 \div \frac{15}{2}[/tex]

= [tex]\frac{64.4 \times 2}{15}[/tex]

= 8.58

Since, we have to round to the nearest tenth.

Therefore, the bear's weight change per month is 8.6 pounds.
