Mercury · Answer

in general, percent error = (predicted value - actual value) / (actual value) * 100%

so for Chelsea, she guessed 87 when there were actually 85 animals ---> (87-85)/(85)*100%

for Aziz: I believe they are considering both a +5 and -5% error, in which case, simply calculate 760 +/- (5% of 760). let the + value be your upper bound and the - value be your lower bound.
