选项

解析
You can translate the given information into an algebraic equation. If Marie walks m miles, she earns 0.75m dollars. Since you know that she earned a total of $18, you get 0.75m =18. Solving for m, you have m =18/0.75= 24. Thus the correct answer is Choice E.
This explanation uses the following strategy.
