Peter work 57 hours, so he works 17 hours of overtime because
57 - 40 = 17
Then, he earns $10.97 per hour, so for the first 40 hours, he earns a total of
40 x $10.97 = $438.8
To calculate the earning for the overtime hours, we need to multiply the normal salary per hour to 1.5 which is the usual rate, so for the overtime hours, he earns:
17 x $10.97 x 1.5 = 279.735
Therefore, the gross pay is
$438.8 + $279.735 = $718.54
So, the answer is $718.54
