the profit p(x)

Question

the profit p(x) generated after producing and selling x units of a product ia given by the function p(x)=r(x)-c(x) where r and c are the revenue and cost functions, respectively. a local sandwich store has a fixed weekly cost of 525.00 and variable costs for making a roast beef sandwich are 0.65 complete parts a through c

Answer 1

The profit function is needed!!!

Let T be the price of each sandwich.

The revenue function is R(x) = Tx

The cost function is C(x) = 0.65x + 525

then p(x) = Tx- (0.65x+525)

= (T-0.65)x - 525

The break-even is 525/(T -0.65)
