(E) Find the profit function in terms of x. . (F) Evaluate the marginal profit at x = 250 and r = 475 and interpret the results. 5) Revenue, cost, and profit. A company is planning to manu- facture and market a new two-slice electric toaster. After conducting extensive market surveys, the research department provides the following estimates: a weekly demand of 200 toasters at a price of $16 per toaster and a weekly demand of 300 toasters at a price of $14 per toaster. The financial department estimates that weekly fixed costs will be $1,400 and variable costs (cost per unit) will be $4. (A) Assume that the relationship between price p and de- mand x is linear. Use the research department's estimates to express p as a function of x and find the domain of this function. (B) Find thc rcvcnuc function in terms of x and state its do- main. (C) Assume that the cost function is linear. Use the financial department's estimates to express the cost function in (D) Graph the cost function and revenue function on the same coordinate system for 0 Sis 1,000. Find the break- even points and indicate regions of loss and profit
