Jeanne is opening a shop and plans to sell cakes. the cost, in dollars, of producing x cakes can be represented by c(x). the revenue, in dollars, brought in by selling x cakes can be represented by r(x). jeanne claims that she will need to sell 300 cakes in order for the cost of producing cakes to equal the revenue brought in by selling the cakes. select three methods that can be used to prove jeanne’s claim. a. graph y = c(x) and y = r(x), and show that the intersection point is (k, 300) for some k. b. graph y = c(x) – r(x) and y = 0, and show that the intersection point occurs when x = 300. c. graph y = c(x) – r(x), and show that the x–intercept occurs at the point (300, 0). d. graph y = c(x) and y = r(x), and show that the intersection point is (300, k) for some k.
