Homework: Section 4.2 Question 15, 4.2.101 HW Score: 57.92%, 9.27 of 16 Homework Part 1 of 5 points Points: 0 of 1 Save Economists use demand functions to describe how much of a commodity can be sold at varying prices. For example, the demand function D(p) = 350 -25p says that at a price of p = 5, a quantity of D(5) = 225 units of the commodity can be sold. The elasticity E - dD p do D of the demand gives the approximate percent change in the demand for every 1% change in the price. Complete parts (a) through (d) a. Compute the elasticity of the demand function D(p) = 350 -25p. E(P) =
