f. If a 2 percent decrease in the price of strawberries increases the quantity demanded of strawberries by 6 percent and increases the quantity of whipped cream demanded by 5 percent, calculate: i. Price elasticity of demand for strawberries.

(1 mark for correct calculation, I mark for interpretation). 6% ------=3 Price elasticity of demand for strawberries is relatively elastic. -2%

ii. Cross elasticity of demand for whipping cream with respect to the price of strawberries. (1 mark for correct calculation, I mark for interpretation).

Solutions

Expert Solution

a-

Price elasticity of demand for Strawberry = % change in quantity demanded for Strawberry/ % change in price of strawberry = 6/(-2) = -3

It means if price of strawberry increase by 1% its quantity demanded will decrease by 3% and demand is elastic here.

b-

Cross price elasticity of demand = % change in quantity demanded for whipped cream/ % change in price of strawberry = 5/(-2)= -2.5

It means that if price of strawberry increases by 1% then quantity demanded for whipped cream decreases by 2.5%. It also suggests that whipped cream and strawberry are complements.

When demand is very elastic then if price rise then the quantity demanded will decrease in...
When demand is very elastic then if price rise then the quantity demanded will decrease in a big amount. When supply is very inelastic then if the sellers' received amount fall due to tax then the quantity supplied will not decrease too much. Hence if demand is very elastic and supply is very inelastic then consumers will bear a small amount of whole tax burden where producers will bear a large amount of whole tax burden. Now, if demand is...

According to the law of demand, if price increases, quantity demanded of a good or service will decrease or vice versa. Price elasticity of demand tells us how much quantity demanded will decrease when price increases or how much quantity demanded will increase if price decreases.On the other hand, according to the law of supply, if the price increases, quantity supplied of a good or service will increase. Similarly, if price decreases, quantity supplied will decrease. The degree of sensitivity...
