Question

Each participant must pay $14 to enter the race. Each runner will be given a T-shirt that cost race organizers $3.50. If the T-shirt was the only expense for the race organizers, which of the following expressions represents the proportion of the entry fee paid by each runner that would be donated to charity? is it $14.00÷($14.00-$3.50)

Answer 1

From the statement of the problem, we know that each participant:

• pays $14 to enter the race,

,

• receives a T-shirt that cost $3.50 to the organizers.

The earnings minus the cost of the T-shirts will be donated to charity, so for each participant, the donation will be $14 - $3.50. So the proportion of the entry fee paid by each runner that would be donated to charity is:

`(14.00-3.50)/(14.00)`

Answer

A. ($14.00 - $3.50) / $14.00
