Gymnast Clothing manufactures expensive soccer cleats for sale to college bookstores in runs of up to 500. Its cost (in dollars) for a run of x pairs of cleats is

C(x) = 3000 + 9x + 0.1x2 (0 ≤ x ≤ 500).

Gymnast Clothing sells the cleats at $130 per pair.

Find the revenue and profit functions.

How many should Gymnast Clothing manufacture to make a profit?

What is the break even cost?

(by using the formula

Revenue is price * units sold

Profit is revenue-cost

how do find the I break the equation, revenue and profit function?

I don't know how to break the equation given.

Thank you
