Answer:
- 3 rides
- $16.50
Step-by-step explanation:
The plan 1 cost for x rides will be ...
y = 6 + 3.50x
The plan 2 cost for x rides will be ...
y = 12 + 1.50x
These costs will be equal when ...
y = y
6 + 3.50x = 12 + 1.50x . . . . . substitute for y
2.00x = 6 . . . . . . . . . . . . . subtract 6+1.50x
x = 3 . . . . . . . . . . . . . . . divide by 2
For 3 rides, the cost will be the same.

For 3 rides the cost is ...
y = 6 + 3.50(3) = 6 + 10.50 = 16.50
The cost for 3 rides will be $16.50 for either plan.
