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 (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 / 7 (1)/(2)`

=
`64.4 / (15)/(2)`

=
`(64.4 * 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.
