Finding a Break-Even Point

A company sells sports helmets. The company incurs a one-time fixed cost for $250,000. Each helmet costs $120 to produce, and sells for $140.

ⓐ Find the cost function, $C,$ to produce $x$ helmets, in dollars.
ⓑ Find the revenue function, $R,$ from the sales of $x$ helmets, in dollars.
ⓒ Find the break-even point, the point of intersection of the two graphs $C$ and $R .$
