Answer:
4 hours
Step-by-step explanation:
First we need to subtract the one pay fee (the helmet rental fee, $15)
So 51 - 15 = 36
Then we need to divide 36 by the amount of money it costs for each hours to find how many hours he rented the bike
So 39/9 = 4
24 laps
1 hour = 60 minutes
4/10 x 60 = 24
16 +28+32+4=80 80 total coins x.15 =12 coins sold
Try using socratic that will help too
Erm 11 isn’t a factor of 64..?
