(b) What is her profit if she sells 5000 units? (c) What is the break-even point for sales? Don't know where to begin. This question is from textbook beginning algebra Answer by tutorcecilia(2152)   (Show Source): You can put this solution on YOUR website! First the formula for finding the profit is given. P(x) = 2.25x - 7000 P(x) = the total profit earned (once you plug in the value of x) x = the number of units . You need to just plug in the number of units for "x". (a) What is her profit if she sells 2000 units? P(x) = 2.25(2000) - 7000 = -\$2,500 (loosing money) . (b) What is her profit if she sells 5000 units? P(x) = 2.25(5000) - 7000 = \$4,250 (profit) . (c) What is the break-even point for sales? Sorry, this one I am not sure of!!
