Final answer:
Mick's gross earnings for the week would be $495.70.
Step-by-step explanation:
To calculate Mick's gross earnings for the week, we need to determine the number of regular units and the number of overtime units he assembled. He is paid $0.88 for the first 521 units, so his earnings for those units would be:
Regular units = 521
Regular earnings = Regular units * Regular rate = 521 * $0.88 = $457.48
His earnings for the overtime units can be calculated as:
Overtime units = Total units - Regular units = 29
Overtime earnings = Overtime units * Overtime rate = 29 * ($0.88 * 1.5) = $38.22
Therefore, Mick's gross earnings for the week would be:
Gross earnings = Regular earnings + Overtime earnings = $457.48 + $38.22 = $495.70
