if I get played 9$ an hour and I work 8:15 a day how much do I get for 5 days

First of all, 15 minutes is 1/4 of an hour.  So 8:15 is 8.25 hours.(8.25 hours/day) x ( 9 $/hour) x (5 days) = $371.25

so first you multiply 9*8=72and then you find how much is 15 min of an hour which is 1/4and 1/4 of a dollar is 25 cents so you would get payed  $72.25
