Alex worked 48 hours last week. He earns $12.50 per hour plus overtime, at the usual rate, for hours exceeding 40 hours.

What is his gross pay?

650

600

550

500

Alex's gross pay is $650.

Step-by-step explanation:

Since Alex worked 48 hours last week, 40 were at his hourly rate of $12.50 and 8 were at his overtime rate of $18.75 (time and a half, or 12.50 + 6.25). We can set up an equation to solve for the total amount that Alex earned for work last week:

40 (12.5) + 8 (18.75) = gross pay

500 + 150 = $650
