Question

A Company makes and sells sailboats.  The company's cost function in thousands of dollars is C(x)=2x+20, and the revenue function in thousands of dollars is R(x) =4x, where x is the number of sailboats.  Evaluate and interpret C(5).

me · Answer

C(5) would be the cost to make 5 sailboats, so substitute 5 for 'x' (2 * 5) + 20 10 + 20 = 30; since the question says the cost is in thousands of dollars, then C(5) is how much it costs the company to make 5 sailboats, which is $30,000 or $6,000 / sailboat.
