  1. Answer:

    60 miles

    Step-by-step explanation:

    Create an equation where y is the total cost and x is the number of miles traveled.

    0.8x will represent the cost from the miles traveled. 8.5 will be added to this to represent the taxi cost and additional charge from tolls:

    y = 0.8x + 8.5

    Plug in 56.50 as y and solve for x, the number of miles:

    y = 0.8x + 8.5

    56.5 = 0.8x + 8.5

    48 = 0.8x

    60 = x

    So, you can travel 60 miles
