Question

u earn $7.50 an hour. at the end of the year u figure out that on a weekly basis u averaged 5 hours of overtime for which u were paid time and a half. how much did u make for the entire year? (assume that a regular workweek is 40 hours)

Answer 1

$18,525, assuming 52 work weeks.

$7.50 * 40 regular hours = $300 a week
$11.25 * 5 hours overtime = $56.25 a week

$300 + $56.25 = $356.25 per week

$356.25 * 52 weeks = $18,525
