Answer: she can rent the bike for a maximum of 13 hours.
Step-by-step explanation:
Let h represent the number of hours for which she rents the bike.
The equation used by Janis to find the total cost, C, in dollars, of renting a bike for h hours is expressed as
C = 4h + 8
If Janis does not spend more than $60, then it means that
4h + 8 ≤ 60
4h ≤ 60 - 8
4h ≤ 52
h ≤ 52/4
h ≤ 13
Therefore, the maximum number of hours for which she can rent the bike is 13.
