Helen earns $7.50 an hour at her job, but if she works more than 35 hours in a week, she is paid 1 1/2 times her regular salary for the overtime hours worked. One week her gross pay was $307.50. How many overtime hours did she work that week?

Respuesta :

7.50 * 35 = 262.50

307.50 - 262.50 = $45.00

7.50 * 1.5 = $11.25

45 / 11.25 = 4 OT hours
