Answer:
The answer is $492.88. This is Marvin's gross pay for the week, calculated by multiplying his hourly wage of $14.75 by the number of hours he worked, which is 33.5 hours.
Explanation:
Marvin works 6 hours a day on Monday through Thursday, for a total of 6 * 4 = <<64=24>>24 hours.
On Saturday he works 8.5 hours, for a total of 24 + 8.5 = <<24+8.5=32.5>>32.5 hours.
Marvin works for 30 minutes unpaid during the week, and 30 minutes unpaid on Saturday for a total of 30 * 2 = <<302=60>>60 minutes.
In hours, 60 minutes is 60 / 60 = <<60/60=1>>1 hour.
Therefore, Marvin works for a total of 32.5 + 1 = <<32.5+1=33.5>>33.5 hours in a week.
Marvin earns $14.75 per hour, so his gross pay is 14.75 * 33.5 = $<<14.75*33.5=492.88>>492.88
