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.

a. Write an equation in standard form that models the possible combinations of bus and subway rides with the same total cost as the pass.

Let b = the number of bus rides

Let s = the number of subway rides

b. 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?
