Let D(x) be the demand (in units) for a new product when the price is x dollars. (a) Write sentences interpreting the following. (i) D(4.25) = 200 When the price is $ 4.25 the demand is 200 units. (ii) D'(4.25) = -10 When the price is $ 4.25 the demand is decreasing by 10 per dollar of product price. (b) Write a formula for the revenue R(x) generated from the sale of the product when the price is x dollars. Assume demand is equal to the number sold. O R(x) = x + D(x) O R(X) = x · D(x) O R(X) = D(x) O R(x) = x - D(x) O R(x) = x + x• D(x) (c) Calculate R'(x) when x = 4.25. R'(4.25) = $ X per dollar Enter an exact number. Interpret R'(x) when x = 4.25. When the price is $ the revenue generated from the sale of the product is -Select-- by $ per dollar of price.
