#6 Points possible: 1. Total attempts: 6 ZWat Inc. manufactures and sells lamps. The company plans to introduce a new model ceiling lamp. The revenue and cost functions are shown in the graph below. Both revenue and cost are in dollars. Use the graph to find the profit (or loss) if lamps are manufactured and sold. (To indicate a loss, use a negative number. For example, a loss of $80 would be entered as - 80.)

Total attempts: 6 Consider the cost C(x), revenue R(x), and profit P(x) functions for producing and selling a water coolers. Revenue, cost, and profit are in dollars. a. What does C(47) = 2, 000 mean in context? The Select an answer v of producing Select an answer vis $ b. Assume that R(47) = 4, 400. Use part a. to find P(47). P(47) = $ #8 Points possible: 1. Total attempts: 6 The price-demand and cost functions for the production and sales of a Mini-Vacs are given as p(x) = 25 - .25x C(z) = 200 + 5x The price per Mini-Vac p(I) and the cost C(x) are in dollars. a. Find the revenue function in terms of I. R(I) = Preview b. Find the profit (or loss) earned at an output of 20 Mini-Vacs. c. On your own, graph the revenue and cost. Be sure to mark the scale on both axes (fit it to Revenue, which you should graph first), label: y = R(x). y = C(x), the break-even points, the -intercepts of y = R(x), and the y-intercept of y = C(x). d. According to your graph, what is the maximum revenue and at what output level does it occur? Maximum revenue is $ at z =[
