Question

Blake eats two bags of generic potato chips each day. Blake's hourly wage increases from $ 9 to $ 15 , and he decides to stop eating generic chips and instead eats a name-brand potato chip. Use the midpoint method to calculate Blake's income elasticity of demand for generic potato chips. Round your answer to two decimal places.

Answer 1

Answer:

The income elasticity of demand for generic potato chips=-4.00

Explanation:

Elasticity of demand can be defined as a measure of how responsive the demand for a certain good is when the price of that good or service changes. The elasticity of demand is usually negative. A negative elasticity of demand implies that the demand of a good or service reduces with an increase in price. The elasticity of demand can be measured using different methods. The mid-point method will be used in this case. The mid-point method of calculating elasticity of demand is as shown;

E=%Q/%P

where;

E=elasticity of demand

%Q=percentage change in quantity demanded

%P=percentage change in the price

And;

%Q=[(Final quantity-Initial quantity)/{(Final quantity+Initial quantity)÷2}]×100

Final quantity=0

Initial quantity=2

replacing;

[(0-2)/{(0+2)÷2}]×100=(-2/1)×100=-200%

%P=[(Final price-Initial price)/{(Final price+initial price)÷2}]×100

%P=[(15-9)/{(15+9)÷2}]×100=(6/12)×100=50%

E=%Q/%P

replace for %Q and %P

E=-200%/50%

E=-4

The income elasticity of demand for generic potato chips=-4.00
