(1 pt) The demand function for a Christmas music CD is given by x = 0.25(225 p) Where x(measured in units of a hundred) is the quantity demanded per week and p is the unit price in dollars. (a) Evaluate the elasticity at 10. E (10) = (b) Should the unit price be lowered slightly from 10 in order to increase revenue? Enter 1 for Yes or 2 for No. answer = (c) When is the demand unitary. p = (d) What is the maximum revenue? Revenue = (1 pt) Currently, 10,000 people take city buses each day and pay 2 dollars for a ticket. The number of people taking city buses at price p dollars per ticket is given x = 5000/6 - P (a) Evaluate the elasticity at 2. E(2) (b) Currently, the price per ticket is 2 dollars. Should the price be raised in order to increase revenue? Enter 1 for Yes or 2 for No. answer = (c) For what value of p, the demand is unitary. p = (d) What is the maximum revenue? Revenue = = (1 pt) Let y = (x2 + 5) Find the differential dy when x 1 and dx = 0.1 Find the differential dy when x = 1 and dx = 0.02
