Let R(x) denote the revenue (in thousands of dollars) generated from the production of x units of computer chips per day, where each unit consists of 100 chips. (a) Represent the following statement by equations involving R or R': "When 1400 chips are produced per day, the revenue is $22,000 and the marginal revenue is $.45 per chip." (b) If the marginal cost of producing 1400 chips is $1.5 per chip, what is the marginal profit at this production level? . . . (a) Choose correct equations below. O A. R(14) = 22,000, R'(14) = .45 O B. R(14) = 22, R'(14) = .045 O C. R(1400) = 22, R'(1400) = .045
