Answer: $623
=====================================================
Step-by-step explanation:
40 hours * $14 per hour = 560 dollars so far
43-40 = 3 overtime hours
His overtime pay is 1.5 times his regular wage, so it is 1.5*14 = 21 dollars an hour for those extra 3 hours. He earns an extra 3*21 = 63 dollars.
The total he earned was 560+63 = 623 dollars
This amount is before taxes or any other deductions.
