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?
so percent error=[tex] \frac{|actual value-predicted value|}{predicted value} [/tex] times 100 note: |x| means absolute value of x means makes it positive
predicted value=125 actual value=95.99 subaitute [tex] \frac{|95.99-125|}{125} [/tex] times 100=[tex] \frac{|-29.01|}{125} [/tex] times 100=[tex] \frac{29.01}{125} [/tex] times 100=[tex] \frac{2901|}{125} [/tex]=23.208 or about 23%
