So, since the student makes $30 each week, we can disregard the number of hours.
So, we can model this situation by the following equation
9.5h+30
So, if he works 10.25 hrs (15 minutes = .25 of 1 hr) we just plug that number in
[tex]9.5h+30\\9.5(10.25)+30\\127.275[/tex]
Since it's money we round to the nearest cent
So he will make $127.28 Next week
