76) Levi earns $19.60 an hour with time and one-half for hours worked over 8
a day. His hours for a week are 9.25, 8.5, 10.5, 13.5, and 6.25. Determine his
gross earnings for a week.

Regular hours = 8 + 8 + 8 + 8 + 6.25 = 38.25
Overtime hours = 1.25 + 0.5 + 2.5 + 5.5 = 9.75
Regular pay = 38.25 × 19.60 = 749.70
Overtime pay = 9.75 × 19.60 × 1.5 =
286.65
Gross pay = $1036.35
