a. $C(x)=100,000+100x$. b. $R(x)=300x$. c. $500$. This means that the company will break even when they produce and sell 500 bikes.
a. We can write the cost function as $C(x)=100,000+100x$. b. We can write the revenue function as $R(x)=300x$. c. The break-even point can be found by letting $R(x)=C(x)$ or $300x=100,000+100x$ which gives $x=500$. This means that the company will break even when they produce and sell 500 bikes.
