Zielflug [23.3K]

<h3>Answer: $623</h3>

=====================================================

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.
