Explanation:

Problem 17

Step1: Calculate regular pay

$\$11 \times 40 = \$440$

Step2: Find overtime pay amount

$\$506 - \$440 = \$66$

Step3: Calculate overtime hourly rate

$\$11 \times 1.5 = \$16.50$

Step4: Solve for overtime hours

$\text{Overtime Hours} = \frac{\$66}{\$16.50} = 4$

Step1: Convert mixed number to decimal

$1\frac{1}{2} = 1.5$

Step2: Calculate first product

$1.5 \times \$8.40 = \$12.60$

Step3: Multiply by final factor

$\$12.60 \times 7 = \$88.20$

Step1: Calculate first product

$2 \times \$18.40 = \$36.80$

Step2: Multiply by final factor

$\$36.80 \times 12 = \$441.60$

Answer:

4 hours
