Answer options:

Quantity demanded will increase by 15%.

How to approach this question

Interpret elasticity: |E| > 1 is Elastic. |E| < 1 is Inelastic. If Elastic: Price and Revenue move in OPPOSITE directions. If Inelastic: Price and Revenue move in SAME direction.

Full Answer

B.Total revenue will decrease.✓ Correct
Price Elasticity of Demand = % Change in Quantity / % Change in Price. <br/>-1.5 = % Change Q / +10%. <br/>% Change Q = -15%.<br/>Revenue = Price x Quantity. <br/>New Revenue = (1.10 P) x (0.85 Q) = 0.935 PQ. <br/>Revenue decreases to 93.5% of the original level.
