Question

Shea's mother wanted to get him a doctor's bag for a graduation present. She thought it would cost $125, but the actual cost was $95.99 . What is the
percent error between her estimate and the actual cost?

Answer 1

So percent error=$\frac{|actual value-predicted value|}{predicted value}$ times 100
note: |x| means absolute value of x means makes it positive

predicted value=125
actual value=95.99
subaitute
$\frac{|95.99-125|}{125}$ times 100=$\frac{|-29.01|}{125}$ times 100=$\frac{29.01}{125}$ times 100=$\frac{2901|}{125}$=23.208 or about 23%

the answer is 23%
