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. Find and simplify the profit function, P(x). How many boats must be sold for the company to break even ( that is, for the profit to be zero)?

Answer 1

P = R - C
P = 4 x - 2 x - 20

P = 2 x - 20

for 0 profit, x = 10

Answer 2

P = R-C = 4x - (2x+20) = 2x-20
When P=0, x=10

Answer 3

Thank you so much
