Necessities tend to have price inelastic demands, whereas luxuries have price elastic demands.

At a price of $2.00 per kilo, 1500 kilos of kiwifruit are supplied and at a price of $3.00 per kilos, 2500 kilos of kiwifruit are supplied. What is the price elasticity of the supply of kiwifruit between these two prices, using the midpoint formula?
