If a binding price floor is in place and if the demand curve for the product shifts rightward, one consequence would be O a decrease in the amount of excess demand O a decrease in the quantity exchanged an increase in the amount of excess supply O an increase in the amount of excess demand O a decrease in the amount of excess supplyIf the total expenditure on photocopiers increases when the price of photocopiers rises, the price elasticity of demand is equal to one (demand is unit elastic). O not determinable from the information given. O greater than one (demand is elastic). O less than one (demand is inelastic). O exactly zero
