The shoe store expected to sell at least 95 pairs of shoes one weekend, but they only sold 77 pairs. What was the approximate pe
Gwar [14]
The error of percentage is the amount of error over the original amount.

In this case it is 22/95  (not 22 over 77 because 77 is not the original amount they expected to sell.
