The students at a community center are participating in a bike riding fundraiser at a local park. A local company is donating $1.75 per mile for each rider. The students have a choice of four different trails to ride. If they choose all four trails, how much money would one student earn for the fundraiser?

This can not be properly answered, because we do not have the length of each trail.

The first step here will be find the length, in miles, for each of the four trails.

As students choose all four trails, the number of miles that each student will bike is equal to the addition of the lenght of the four trails.

Suppose this number is N.

So each student bike N miles, and the company donates $1.75 per mile. Then the amount of money that a single student is N times $1.75, or N*$1.75
