So. We know that Mike paid 71 dollars. We also know that NO MATTER WHAT. He has to pay 17 dollars. So 71-17 is 64. Now, all we need to do is divide 64 dollars, by 6 dollars, to give us the number of hours.
64/6 = 10.6
So Mike had the bike for 10.6 (approxamently) hours.

Answer:
- adult: 325
- children's: 225
Step-by-step explanation:
It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...
1.50a +1.00(550 -a) = 712.50
0.50a = 162.50 . . . . . . . . . . . . . subtract 550 and collect terms
a = 325
c = 550 -325 = 225
325 adult and 225 children's tickets were sold.
