Question

James is participating in a 5-mile walk to raise money for a charity. He has received $800 in fixed pledges and raises $13 extra for every mile he walks. Use a point-slope equation to find the amount he will raise if he completes the walk.

Answer 1

The amount that James will raise for the charity is $865.

Explanation:

Total distance to cover = 5 miles.

He had received $800 in fixed pledges, and raises $13 for every mile he walks. Let the mile he walks be represented by d, and the amount he would raise by A.

So that,

A = $(13d + 800)

But, d = 5 miles.

thus,

A = $(13 x 5 + 800)

= $865

Thus,

amount he would raise = $865

James would be able to raise $865 for the charity after the walk.
