Question
The demand function for electric fans is as follows:
• Qx = 100 – 0.5Px + 0.03I + 3Py where:
• Qx = quantity demanded of electric fans
• Px = average
• I = average income
• Py = average price of an air conditioner
Assume that the average price of an electric fan is $50, an air conditioner costs
$400 and average income is $4,000.
Determine or calculate the following:
1. The slope of the demand curve,
2. If air-conditioners are complimentary or substitutionary to electric fans
with respect to the coefficient and,
3. If electric fans are a normal or inferior good with respect to the income
coefficient.

- a) Suppose the price of flour increases from $0.60 to $1.10 a pound and the quantity demanded decreases from 100 pounds to 60 pounds. Using the midpoint method, what is the price elasticity of demand for flour? Is the demand for flour elastic or inelastic? b) A 15 percent increase in income brings about a 25 percent decrease in the demand for a good. What is the income elasticity of demand and is the good a normal good or an inferior good?arrow_forwardAssume that in Country A, the average annual income of a typical person is $180,000. Annual consumption of black caviar is estimated at 4.5 kilos. The income elasticity of demand for black caviar is 1.25.
