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.
Answer:
Janis could rent the bike for 13 hours.
Step-by-step explanation:
Given the equation C = 4h + 8, and the information that Janis will NOT spend more than $60 we can say that:
Step 1
We will substitute the C for the maximum amount of money she will spend ($60)
So the equation will be: 60 = 4h + 8
Step 2
We need to isolate the variable by subtracting 8 to both sides of the equation to maintain the equality. We subtract because the equation is adding.
60 - 8 = 4h + 8 - 8
Therefor: 52 = 4h
Step 3
For the final step, we need to isolate the variable h, but this time, because the variable is being multiply by the 4, we need to divide by 4 on each side of the equation:
52 / 4 = 4h / 4
So 13 = h, or h = 13
