Towel Problem
A discount store bought a quantity of towels for $250. They sold all but 15 at a profit of $3.50 per towel. With what he received, the manager was able to buy 4 more than twice the number of towels as he originally purchased. What is the cost per towel?

Re: Towel Problem
The cost per towel (to the store) is $2.50.
let n = number of towels purchased originally let p = price of towels purchased np = 250 (n-15)(p+3.5) = (2n+4)p Solve this system of equations, you should get p = 2.5. |

Re: Towel Problem
Good work polarbear. The key is recognizing that what he received on the towels he sold was both his profit and his cost (p + 3.5). Most of the students in my study group tried to solve the equations using 3.5(n-15) as the amount received.
