A clerical assistant earns \(\$45.20\) in 8 hours. At this rate, how much does he earn in 40 hours?
\(\$226\)
Explanation
Set up a proportion and solve for the missing term.
\(\frac{\text{hours}}{\text{amount earned}}= \frac{8}{\$45.25}=\frac{40}{x}\)
\(8 x=45.20 \times 40\)
\(8x = 1,808\)
\(x = 226\)
So, a clerical assistant earns \(\$226.00 \) in 40 hours.
