Question

Mrs. Nguyen thought that she had $40 in her wallet. She actually has $48. What is her percent error? (Round to the nearest percent.)

Answer 1

Answer: 17%

Step-by-step explanation:

Her guess is off by 8 dollars (since 48-40 = 8) and this is out of the true value of 48

So 8/48 = 1/6 = 0.1667 = 16.67% approximately is the percent error

This rounds to 17%
