Answer:
Step-by-step explanation:
a.
Initial value of the pass is $100
From the difference in values we can see the cost of one ride is $1.75
The formula:
- P(r) = 100 - 1.75r, P- the value of the pass, r- the number of rides
Value of the pass after 15 rides:
- P(15) = 100 - 1.75*15 = 73.75
b.
Number of possible rides:
- 0 = 100 - 1.75r
- 1.75r = 100
- r = 100/1.75
- r = 57 (rounded to the whole number)
