City Transit Equation Planner

Write proportional equations for bus and subway plans.

Build the Fare Models

Use the planner's fares, not fares from your own city. There are no extra fees or free transfers. Choose or complete each equation.

1.
The subway charges the same fare for every ride. Let n be the number of rides and t be the total cost in dollars. Which equation models the table?
Subway Fares
Rides, nCost, t ($)
26
515
721
  • A. t = n/3
  • B. t = 6n
  • C. t = n + 3
  • D. t = 3n
2.
A bus ride costs $2.25. Let n be the number of bus rides and t be their total cost in dollars. Complete the equation.

t =  n

3.
Subway rides cost $3 each. Let n be the number of rides and t be the total cost in dollars. Select every equation that correctly relates n and t.

t = 3nn = 3tt/n = 1/3, for n > 0n = t/3
