please help me wit question C and E

C) Use the price elasticity of demand above, If Starbucks decreases its price by 10 percent, the quantity demanded for Starbucks coffee: (thow your calculation). a. Increases by 28% b. Decreases by 6.5% c. Decreases by 2% d. Increases by 56% D) Using the price clasticity of demand above, if Starbucks increases its price by 5 percent, the quantity demanded for Starbucks coffee: (show your calculation) a. Increases by 1.8% b. Docreases by 56% Now the price has increased by 10% Change the demand =5.610%=56% The demand will be dropped by 56% c. Decreases by 28% d. Increases by 10% E) Refer to the graph above. Suppose that between point D and E on Starbucks demand curve for coffee, price falls by 66% and quantity demanded Increases by 12%. Calculate the price elasticity of demand between point D and E. Show elasticity calculation work below. a. Ep=67% c. Ep=1.2 b. Ep=0.18 d. Ep=12%
