Question

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.

Answer 1

Total pounds of weight loss of bear in $7 \frac{1}{2}$ 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 = $64.4 \div 7 \frac{1}{2}$

= $64.4 \div \frac{15}{2}$

= $\frac{64.4 \times 2}{15}$

= 8.58

Since, we have to round to the nearest tenth.

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