You might need a calculator.

Three employees each clocked a different number of hours worked this week.

\begin{tabular}{|ccc|}
\hline Employee & Total earnings (in dollars) & Hours of work \\
\hline A & 180 & 15 \\
B & 210 & 20 \\
C & 455 & 35 \\
\hline
\end{tabular}

Which employee has the highest earnings per hour?

Choose one answer:
(A) Employee [tex]$A$[/tex]
(B) Employee [tex]$B$[/tex]
(C) Employee [tex]$C$[/tex]



Answer :

To determine which employee has the highest earnings per hour, we need to calculate the earnings per hour for each employee. We will do this by dividing the total earnings by the number of hours worked for each employee.

Here are the steps:

1. Calculate earnings per hour for Employee A:
- Earnings: \[tex]$180 - Hours worked: 15 - Earnings per hour \(= \frac{180}{15} = 12.0\) dollars per hour 2. Calculate earnings per hour for Employee B: - Earnings: \$[/tex]210
- Hours worked: 20
- Earnings per hour [tex]\(= \frac{210}{20} = 10.5\)[/tex] dollars per hour

3. Calculate earnings per hour for Employee C:
- Earnings: \$455
- Hours worked: 35
- Earnings per hour [tex]\(= \frac{455}{35} = 13.0\)[/tex] dollars per hour

Now we compare the earnings per hour for each employee:

- Employee A: 12.0 dollars per hour
- Employee B: 10.5 dollars per hour
- Employee C: 13.0 dollars per hour

From these calculations, we can see that Employee C has the highest earnings per hour at 13.0 dollars per hour.

Therefore, the employee with the highest earnings per hour is:

(C) Employee C
