Please help!!! Here is the problem:

The profit p (in thousands of dollars) on x thousand units of a specialty item is p = 0.8x - 15.5. The cost c of manufacturing x items is given by c = 0.6x + 15.5 .

Find an equation that gives the revenue r from selling x items.

How many items must be sold for the company to break even (i.e., for revenue to equal cost)?

Round to the nearest integer.
