if the edge measurements have a tolerance of $ 2 ft. 3.0] 52. Economics: elasticity of demand. Schneider's Bakery sells cakes. At a price of $20 per cake, it sells 300 cakes per week. At a price of $50, it sells 150 cakes per week. [3.7] a) Find a linear demand function D(x) that models this situation. b) Find the elasticity of demand. c) Find E(20) and E(50), and explain what these num- bers represent. d) Using the linear demand function from part (a), find the price x that results in unit elasticity, and explain what this number represents. Also, determine the weekly revenue at this price. e) Find an exponential demand function of the form y = Poe kx f) Using the demand function from part (e), find the price x that results in unit elasticity, and explain what this number represents. Also, determine the weekly revenue at this price
