Answer: $600.75
Step-by-step explanation: First find how much Gerald will earn for working 40 hours. (13.50 x 40) = 540 Next you need to find what his time and a half pay is by finding what half of 13.50 is and adding it to 13.50
(13.50 x 1/2) = 6.75 (6.75 + 13.50) = 20.25
Now multiply 20.25 by his overtime hours (3) and add that to 540
