#3
What does the term 'elasticity of demand' measure?

ExplanationCost of production is not a determinant; demand factors include income, preferences, and substitutes.
#6
In a perfectly competitive market, what is true about the demand curve facing an individual firm?

#8
Which of the following is a characteristic of monopolistic competition?
Mutual interdependence among firms
ExplanationFirms in monopolistic competition influence each other due to product differentiation.
#9
Which of the following factors does NOT affect the elasticity of demand for a good?

ExplanationCross-price elasticity quantifies the impact of price changes in one good on the demand for another.
#12
