-Refer to Figure 5-9.Suppose this demand curve is a straight,downward-sloping line all the way from the horizontal intercept to the vertical intercept.We choose two prices,P₁ and P₂,and the corresponding quantities demanded,Q₁ and Q₂,for the purpose of calculating the price elasticity of demand.Also suppose P₂ > P₁.In which of the following cases could we possibly find that (i) demand is elastic and (ii) an increase in price from P₁ to P₂ causes an increase in total revenue?

A) 0 < P1 < P2 < $10.
B) $10 < P1 < P2 < $15.
C) P1 > $15.
D) None of the above is correct.
