Question

Lauren's salary decreases from $34,000 to $30,000. She decides to reduce the number of outfits she purchases each year from 20 to 19 . Use the midpoint method to calculate the income elasticity of demand for new outfits. Round your answer to two decimal places.

Answer 1

Answer:

8.08

Explanation:

Hi!

The income elasticity of demand is calculated by dividing the negative % change in demand by the % change in real income.

We calculate the negative % change in demand as:

19/20 = 0.95, a 95%

Then, the % change in real income as:

(34,000-30,000)/34,000 = 0.1176, an 11.76%

So the income elasticity of demand is:

0.95/0.1176 = 8.08

Hope it helps! :)
