Michael earns $21 per hour and works 40 hours per week. How many overtime hours would he have to worky in a week for his time-and-a - half overtime pay to be greater than his regular gross pay? Explain your answer.

27 hours

Step-by-step explanation:

The regular hours are paid normally, 21/hr hence working for 40 hours, Michael earns 40*21=$840

To work x hours paid overtime as 1.5 of the normal rate, the rate would be $21*1.5=$31.5/hr

X hours multiplied by rate of $31.5/hr should be at least equal to $840

31.5x>=840

X>=840/31.5>=26.6667 hours and when rounded off

X is 27 hours
