Normal good

Explanation:

SOLUTION

Using the midpoint method to calculate her income elasticity

Ei=(Q2-Q1) /(I2-I1)*(I2+I1)/(Q2+Q1)

Q2=4 I2=109,500

Q1=3 I1=100,500

Ei=(4-3)/(109,500 - 100,500) *(109,500+100,500)/(4+3)

Ei=1/9000*210,000/7

Ei=3.33333333

Approximate to two decimal places

Ei=3.33
