Question

Alan estimated that he would score 140 points the next time he bowled. He actually scored 152 points. What was the percent error in Alan’s estimate? Round to the nearest tenth of a percent, if needed.

Answer 1

The answer is 213%. you multiply 140 by 152 and dividr

Answer 2

Given:
estimate = 140
actual = 152

Percent of error = |(estimate - actual)/actual|  * 100%

% of error = |140 - 152| / 152 * 100%
                 = |-12|/152 * 100%
                 = 0.0789 x 100%
% of error = 7.89%  rounded to the nearest tenth 7.9%
