Answer:
A. y = 0.50x + 12
y = 1.25x
Step-by-step explanation:
The equation that model the total cost of plan A is:
y = 12 + 0.50x
Because there is a cost of $12 that is independent of the number of rides x and there is a cost of $0.5 for each ride.
In the same way, the equation that model the total cost of plan B is:
y = 1.25x
Because there is only a cost of $1.25 for each ride.
Therefore, the system of equations that could be used to choose a ticket plan is:
A. y = 0.50x + 12
y = 1.25x
