Solution:
What we are looking for: 
"We are looking for the equation that represents the proportional relationship between the total cost, T, and the number of binders, n."

How to form the equation which represents the proportional relationship:
We would divide 24 by 8 to determine the price of each individual binder, using that we would form our equation.
