alex's gross pay is $650.
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
