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 :-
