I need help solving the following:

A guitar factory has fixed production cost of $50,000 plus $75 for each guitar produced. Its cost of production function can be written as C(x) = 75x + 50,000.

The company decides to sell each guitar for $325, so its revenue function can be written as R(x) =325x.

How many guitars must the company sell at $325 per guitar in order to "break even"?

I solved the problem but im not sure if my answer is correct
