Question

A female grizzly bear weighs 500 pounds. After hibernating for 6 months, she weighs only 350 pounds. What is the mean monthly change in weight?

Answer 1

Step 1: Difference in weight before and after hibernation

Given, Weight of female bear before hibernation $=500$ pounds

Weight of female bear after 6 month of hibernation $=350$ pounds

$=500-350$ pounds

$=150$ pounds

Step 2: Mean monthly change in weight

$=\frac{150}{6}$$=25$ pounds

Hence, Mean monthly change in weight $=25$ pounds
