Question 198734: Please Help!
The cost (C) of selling x calculators in a store is modeled by the equation:
C= 3,200,000/x + 60,000. The store profit (P) for these sales is modeled by the equation: P = 500x. What is the minimum number of calculators that have to be sold for profit to be greater than cost?
Thanks!

Set the profit function equal to the cost function and then solve for x.
