We are given : Rate for regular pay = $12 per hour.
Rate for over time = $12 and a half rate of $12, that is 12+ 12/2 =12+6= $18 per hour.
We need to find the total pay for 40 hours of regular time and 10 hours of overtime.
Pay for 40 hours at the rate $12 per hour = 40 × 12 = $480.
Pay for 10 hours of overtime at the rate $18 per hour = 10 × 18 = $180.
Total payment for 40 hours of regular time and 10 hours of overtime = 480 + 180=$660.
Therefore total pay or 40 hours of regular time and 10 hours of overtime is $660.
