Question

# Determine each estimate without using a calculator. Then use a calculator to perform the computation necessary to obtain an exact answer. How reasonable is your estimate when compared to the actual answer? If a person who works 40 hours per week earns \$61,500 per year, estimate that person's hourly wage.

Solution

Verified
Step 1
1 of 2

The person earns

$\61,500$

He works

$40\textrm{ hours/week}$

i.e. The person works

$40 \frac{hours}{week}\times\frac{52week}{years}=2,080hours/year\approx2000hours/year$

i.e. It can be estimated that the person's hourly wage is

$\61,500\div2000=\30.75\approx\31$
