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:
C(m) = Cost per mile * m + flat rate
C(m) = 0.65m + 1.75

The problem asks for m when C(m) = 10
0.65m + 1.75 = 10

Typing this equation into the search engine, we get:
m = 12.692 miles
