Question 7.

**H.O.T.** Emily is a pharmacist. She earns $50 per hour. If she works on a holiday, she gets paid double the hourly rate. Last week she worked for 38 hours, including 8 hours on a holiday. Emily’s salary is her only source of income.

If her net income last week was $1,947, how much was her payroll tax? Explain.

Answer:

Emily earns $50 per hour. Last week she worked for 38 hours, including 8 hours on a holiday.

1 hour = $50

30 hours = $?

**$50 x 30 = $1,500**

If she works on a holiday, she gets paid double the hourly rate.

1 hour = $100

8 hours = $?

**$100 x 8 = $800**

Emily earns $800 for 8 hours on a holiday.

Emily’s Gross income = $1,500 +$800 = **$2,300**

If her, net income last week is **$1,947**.

Emily’s Payroll tax = Gross income – Net income

Payroll tax = $2,300 – $1,947 = **$353**

Explanation:

Emily is a pharmacist. She earns $50 per hour. If she works on a holiday, she gets paid double the hourly rate. Last week she worked for 38 hours, including 8 hours on a holiday.
