Question

Wisin estimated his cell phone bill to be $93. His actual bill was $87. What was his percent error?

Answer 1

The percent error is: 6.89%

Step-by-step explanation:

The percent error is given by:

$Percent\ error=\frac{|Expected\ value-Exact\ value|}{Exact\ Value} *100$

Here,

Expected Value = $93

Exact Value = $87

Putting the values in the formula

$Percent\ Error=\frac{|93-87|}{87}*100\\=\frac{|6|}{87}*100\\=0.0689*100\\=6.89\%$

The percent error is: 6.89%
