The income elasticity of demand for steak in Cape Charles is __________.

Answer 1

The income elasticy of demand for steak is 0.5

Step-by-step explanation:

The income elasticity of demand formula is:

IED = Δ%Q / Δ%Y

Where:

• Δ%Q is change in quantity demanded
• Δ%Y is change in income

So for this case:

IED = 2%/4%

= 2/4

= 0.5
