MODELING REAL LIFE One bus ride costs $0.75. One subway ride costs $1. A monthly pass for unlimited bus and subway rides costs the same as 36 bus rides plus 36 subway rides.
Write an equation in standard form that
models the possible combinations of bus and subway rides with the same total cost as the pass.
b. Graph the equation from part (a).
c. You ride the bus 60 times in one month. How many times must you ride the subway for the total cost of the rides to equal the cost of the pass?
Explain your reasoning.
