Answer:
13 miles
Step-by-step explanation:
The taxicab charges a fixed amount of $3.10 plus $0.60 per mile.
This can be modeled by the equation.
[tex]f= 0.60m + 3.10[/tex]
where f is the total fare and m is the number of miles traveled.
If Carmen paid a fare of $10.90, then we substitute for f and solve for m.
[tex]0.6m + 3.10 = 10.90[/tex]
[tex]0.6m = 10.90 - 3.10[/tex]
[tex]0.6m = 7.8[/tex]
[tex]m = \frac{7.8}{0.6} [/tex]
[tex]m = 13[/tex]
Therefore Carmen traveled 13 miles.
