Jackson goes out of town and needs to take a taxi once he arrives to explore the city. He has $65 total to spend on taxi fares, and the taxi charges $3.75 plus an additional $1.25 per mile. The graph below models the number of miles Jackson can travel in the taxi. Write an inequality

Let x be the number of miles Jackson can travel in the taxi.

The total cost of the taxi fare is 3.75 + 1.25x.
According to the problem, Jackson has $65 total to spend on taxi fares, so the inequality is:
3.75 + 1.25x ≤ 65.
