Price elasticity of demand of a good is (-)1. At a given price the consumer buys 60 units of the good. How many units will the consumer buy if price falls by 10 per cent? |
| Answer» GIVEN: Ed = -1, Q1 = 60, % Change in Price = -10% Ed = % Change in Price/% Change in Qty -1 = -10/% Change in Qty % Change in Qty = (-10)/(-1) % Change in Qty = 10 Therefore: % Change in Qty = ΔQ/Q0*100 10 = ΔQ/60*100 ∆Q = 10*60/100 ∆Q = 6 Q1 = ∆Q + Q0 Q1 = 6+60 Q1 = 66 New Qty is 66.
