quantity demanded of another good, then it can be concluded that the two goods are:

quantity demanded of another good, then it can be concluded that the two goods are:
104. A 3 percent increase in the price of tea causes a 6 percent increase in the demand for
coffee. The cross elasticity of demand for coffee with respect to the price of tea is:

of a normal good suggests that:
107. If the demand for a product increases proportionately faster than the increase in
consumers’ incomes, then the income elasticity of demand for the product is:
108. A negative income elasticity of demand coefficient indicates that:

109. The income elasticity of demand for a food is roughly 1. A consumer’s monthly income
is $2,000, of which 20 percent is spent on food. If the income of this consumer doubles, the
amount she’ll spend on food will be:
110. A consumer’s weekly income is $300 and the consumer buys 5 bars of chocolate per
week. When income increases to $330, the consumer buys 6 bars per week. The income
elasticity of demand for chocolate by this consumer is about:

Chapter 04 – Elasticity
122. If the percentage change in quantity demanded is less than the percentage change in
price, then demand is said to be elastic.
123. Along a straight-line demand curve, demand tends to be elastic at lower prices and
inelastic at higher prices.
124. A good with a price-elasticity coefficient of 0.75 has a demand that is price-inelastic.
125. If the quantity demanded for good A increases from 40 to 60 when price decreases from
$9 to $7, price elasticity of demand in this price range is 1.6.
Chapter 04 – Elasticity
126. In the price range where demand is elastic, if the seller of the good raises its price, then
total revenues will increase.
127. If the price-elasticity coefficient for a product is 0.68 and the seller wants to raise
revenues by changing its price, then the seller should cut the price of the product.
128. Whenever a product is put on special sale at a discounted price, total revenue from the
product increases. This indicates that the coefficient of elasticity for the product is greater
than 1.
129. When demand is price-elastic, an increase in price will lead to increased total consumer
spending for the product.
130. Price elasticity of demand tends to be low for goods with few close substitutes.
131. Given: The demand for most agricultural products is inelastic. Therefore, an increase in
supply will increase the total income of producers of agricultural products.
132. A state government seeking to increase its excise-tax revenues is more likely to increase
the tax rate on items with elastic demand.
133. The demand for cocaine among addicts is relatively elastic.
134. One reason the luxury tax on yachts imposed by the U.S. Congress in 1991 failed to
produce much tax revenue was that the demand for yachts was quite inelastic.
135. Price elasticity of supply decreases over a longer time period.
136. The supply of antiques is highly inelastic so increases in demand would have a small
effect on price.
137. If changes in demand cause significant changes in equilibrium price, then supply must be
quite inelastic.

138. The supply of tickets to a major sporting event held in a stadium, such as the Super Bowl
or a World Series game, is perfectly inelastic.

negative.
