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.
