Eric's income increased from $40,000 to $50,000 per year. Eric's consumption of tickets to pro football games increased from two to four per year. By the midpoint formula, his income elasticity of demand for pro football game tickets is equal to , and football game tickets are goods. –3; inferior –0.33; inferior +0.67; normal +3; normal

By the midpoint formula, his income elasticity of demand for pro football game tickets is equal to +3, and football game tickets are normal goods.

Explanation:

The formula for calculating income elasticity of demand using the midpoint method is:

income elasticity of demand = {change in quantity demanded / [(old quantity + new quantity) / 2]} / {change in income / [(old income + new income) / 2]}

= {2 / [(2 + 4) / 2]} / {10,000 / [(40,000 + 50,000) / 2]} = (2 / 3) / (10,000 / 45,000) = 0.67 / 0.222 = 3

when the income elasticity of demand is higher than 1, the goods are normal goods.

hi,

henry is an economist and wants to understand the relationship between inflation and consumer spending habits. for his research, he needs the consumer price index for 2014 and the inflation rate. based on the prices of goods given, what will he find to be the cpi and inflation rate for 2014? assume that a consumer’s basket for three consecutive years consists of the following:

you dont privide answer choices.

answer - 15% of a inflatation rate is 15% less in cpi

answer; yield to maturity;
