10. Hourly Rate

11. Think about this…
Sarah has been offered a new job as an assistant manager in a shoe department. She will work 54 hours each week and earn $15 an hour. For this work schedule and rate of pay, is it possible for Sarah’s gross pay for one month to be at least $3,650?

12. Regular Time Typical work week is 40 hours
Workers receive regular pay for up to 40 hours per week
To calculate pay for regular hours:
Wage = (hourly rate) x (number of hours worked)

13. Example:
Maureen works at a local Chicken King Restaurant. Her regular hourly wage is $ If she regularly works 40 hours per week, what is her regular weekly pay?
Weekly Pay= (hourly rate) x (number of hours)
= (9.70) x (40)
= 388
Maureen makes $388 per week

14. Try it…
Mark Willow works as a customer service representative and is paid $9.10 per hour. He worked 38 hours lat week. What was his gross pay?
Gross pay = (hourly rate) x (number of hours)
= (9.10) x (38)
= 345.8
Mark earned $ last week

15. Overtime Hours worked in a week greater than 40
Usually pays 1.5 times hourly rate
“Time and a half”
How many hours of overtime for:
45 hours?
54 hours?
38 hours?

16. Example:
Janice earns $10 per hour. If her regular hours are 40 hours per week, and she receives time-and-a-half overtime, find her total pay for a week in which she works 45 hours.
Total Pay = Regular Pay + Overtime Pay

17. Calculating Pay Regular Pay Overtime Pay (OT hrs)x(hrly rate)x(1.5)
(Reg. Hrs) x (Hrly Rate)
(40 hours) x ($10)
= $400
Overtime Pay
(OT hrs)x(hrly rate)x(1.5)
(5 hrs) ($10) (1.5)
= $75
Reg Pay = $400
OT Pay = $75

18. Example:
Janice earns $10 per hour. If her regular hours are 40 hours per week, and she receives time-and-a-half overtime, find her total pay for a week in which she works 45 hours.
Total Pay = Regular Pay + Overtime Pay
Total Pay = $400 + $75
= $475

19. Try it…
Kenny Walker works as a shopping mall security guard and is paid $7.50 an hour. He is paid time-and-a-half for all hours over Find his gross pay when he works 46 hours a week.
Gross Pay = Reg. Pay + OT Pay
= $300 + $67.50
= $367.50

20. Think about this…
Sarah has been offered a new job as an assistant manager in a shoe department. She will work 54 hours each week and earn $15 an hour. For this work schedule and rate of pay, is it possible for Sarah’s gross pay for one month to be at least $3,650? Yes, gross pay would be:
$3,660

You work at a store making d dollars per hour. Last week, you worked 35 regular hours and h overtime hours, at time-and-a- half. Write a formula that expresses your weekly pay.
Weekly Pay = 35d + hd(1.5)
= 35d + 1.5hd

60. Writing Formulas
Last week, you worked a total of 52 hours, 40 of which were regular hours. You are paid x dollars per hour and are paid double time for all overtime hours. Your weekly salary was $800. Set up an equation that represents this.

Writing an algebraic expression
Doing any arithmetic that can be done
Combine like terms
Solve the equation (divide)
