A radio manufacturing firm has fixed costs of $25,000 and variable costs of $75.80 per radio. The radio sells for $119.95. Write an expression for the profit function and find the number of radios that must be sold to break even.
-----------------
Cost for x items = 25000+76.80x
Revenue = 119.95x
----
Profit = Revenue - Cost
P = 119.95x - (25000+76.80x)
Profit = 43.15x - 25000
