Question

A zookeeper predicted the weight of a new baby elephant to be 227 pounds when it was born. The elephant actually weighed 259 pounds at birth. What was the percent error of the zookeeper's prediction?

Answer 1

The percent of error can be found by dividing the difference in weights by the predicted weight.

290 - 258 = 32 pounds

32/258 = 0.124

0.124 = 12.4% approximately was the percent of error
