Question

Jalen measured a bookcase to be 8.4 ft the actual measurement is 5.6 ft what is Gary percent error

Answer 1

We start by calculating the difference between the expected measured value and the value measured by Gary:

8.4 ft - 5.6 ft = 2.8 ft

Now we estimate what 2.8 ft is of the actual measurement 8.4 ft. That is:

2.8 / 8.4 = 0.33333... this is written in percent form as: 33.33%

This is the percent error.
