    A taxi charges a flat rate of $1.75, plus an additional $0.65 per mile. If Erica has at most 10$ to spend on the cab ride, how far could she travel

    Set up a cost function C(m), where m is the number of miles Erica can travel. We have:
    C(m) = 0.65m + 1.75

    If C(m) = 10, we have:
    0.65m + 1.75 = 10

    Typing this equation into our search engine, we get:
    m = 12.69 miles

    If the problem asks for complete miles, we round down to 12 miles.
