D(1.25) 1000 When the price is $ the demand is units (ii) D'(1.25) = -50 the demand is Select When the price is $ per dollar of product price. by (b) Write a formula for the revenue R(x) qenerated from the sale of the product when the price is x dollars. Assume demand is equal to the number sold. OR(x) x- D(x) R(x) x D(x) OR(x) Dix) R(x) x x - D(x) R(x) xD(x) (c) Calculate R'(x) when x = 1.25. R'(1.25) $ per dollar Interpret R'(x) when x = 1.25. the revenue generated from the sale of the product isSelect- by $ When the price is $ per dollar of price.
