Hourly Rate

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?

Think about this…

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)

Regular Time

Maureen works at a local Chicken King Restaurant. Her regular hourly wage is $9.70. 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

Example:

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 $345.80 last week

Try it…

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?

Overtime

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

Example:

Calculating Pay

Reg Pay = $400 OT Pay = $75

Regular Pay

(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



Total Pay = $400 + $75

= $475

Example:

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 40. Find his gross pay when he works 46 hours a week.

Gross Pay = Reg. Pay + OT Pay = $300 + $67.50

= $367.50

Try it…

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:

Think about this…

$3,660
