Answer:

18.91 percent

Step-by-step explanation:

Percent error equation:     Difference       or    Difference/Actual

                                            Actual


The difference is the greater amount minus the smaller.

111 - 89 = 22


The actual is 111.


Now divide 22/111.

22/111 = 0.189 repeating


0.189 repeating = about 18.91 percent
