Answer:

  a. $488

  b. 12 hours at $18.30 = $219.60

  c. $707.60

Step-by-step explanation:

a) You correctly computed Brown's straight-time pay. His pay is ...

  40 hours at $12.20 per hour = $488

__

b) Brown's overtime pay is 1.5 times his straight-time pay per hour:

  OT pay rate = 1.5 × $12.20 = $18.30 . . . per hour

The amount of overtime is 52 hours - 40 hours of straight time = 12 hours. Then the overtime pay is ...

  12 hours at $18.30 per hour = $219.60

__

c) Brown's total pay is the sum of straight-time pay and overtime pay:

  $488.00 +219.60 = $707.60 . . . total pay
