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

Inelastic; 5%; fall; 10%; rise

Explanation:

Price elasticity of demand is always negative for normal goods. This happens because of the law of demand, that demand falls with rise in price.

Price elasticity between 0 and 1 shows inelastic demand.

This means that there is smaller change in demand due to a greater change in price level.

Price elasticity of demand is -0.5.

If the price falls by 10%, demand will increase by 5%.

The revenue will fall, because of greater fall in price.

If the price increases by 20%, demand will fall by 10%.

Revenue will increase because of greater increase in price.

the correct answer is:     [c]:     " cyclical unemployment " .
