5/80 = 0.0625
so 6.25% or in your case 6.3%

Answer:

Step-by-step explanation:

Percentage error is calculated by

Percentage error = (estimate-real)/real*100%=(115-82.5)/82.5*100%=28.26%

An over-estimate gives a positive error percent, and an underestimate gives a negative error.

Also, dividing by the real value makes it possible to have more than 100% error.

For example, if real cost is $50, and estimated cost is $150, then error percent is (150-50)/50*100%=200%!

C: 39.4%

Step-by-step explanation:

The formula to calculate the percent error is given by :-

Given: The estimated amount = $115

The actual amount = $ 82.50

Now, the percent of error will be given by :-
