At a specific point on the demand curve for backpacks, the elasticity of demand is calculated to be -0.5.a. At that point, we would describe demand as ( inelastic / elastic / unit elastic / fully supplied ).b. If the price of backpacks fell by 10%, the quantity demanded would rise by (10% /5% / 50% / 0% ) and revenue for the backpack industry would ( fall / rise) remain the same .c. If the price of backpacks rose by 20% the quantity demanded would fall by ( 20% / 10% / 25% / 40%) and revenue for the backpack industry would ( fall / rise) remain the same A school district needs 3 teachers for every 70 students.
