【題目】 Suppose that the price of eggs increases from 75 cents to $1.00 per dozen and as a result a typical farmer experiences a decrease in egg sales from 300 to 200 dozen per week. Using the method of average values, the price elasticity of demand is 3.0 1.4 0.8 1.75
【題目】 Assume that we have a demand curve of the form.log(Q)=a-b×log(P)+c×log(I), where Q=quantity, P=price, I=income, and a, b, and c are positive constants.
