Question

During 7 1/2 months of hibernation, a black bear experienced a weight loss of 64.4 lbs. on average what was the bears weight change per month. Round to the nearest tenth.

Answer 1

Hibernation time: 7 1/2 months = 15/2 months

Weight loss: 64.4 lbs

We can calculate the average weight change per month using the equation:

average_weight_loss = weight_loss / time

We know that:

weight_loss = 64.4 lbs

time = 15/2 months = 7.5 months

Then, using the equation above:

average_weight_loss = 64.4 lbs / 7.5 months

average_weight_loss = 8.5867 lbs/month

To the nearest tenth, the average monthly weight loss of the black bear was 8.6 lbs/month.
