Label the following hypothetical demand scenarios. Use the midpoint method. Contain Yourself!, a plastic container company, raises the price of its signature "lunchbox" container from $3.00 to $4.00. As a result, the quantity sold drops from 20,000 to 15,000.
Economists working for the United States have determined that the elasticity of demand for gasoline is 0.5.
CapCityMetro decides to increase bus fare rates from $2.00 to $2.21. Consequently, the number of passengers who decide to take the bus in Austin drops from an average of 70,000 riders a day to an average of 61,000 riders a day.

Contain Yourself!, a plastic container company, raises the price of its signature "lunchbox" container from $3.00 to $4.00. As a result, the quantity sold drops from 20,000 to 15,000.

UNIT ELASTIC ⇒ when the price elasticity of demand is unit elastic, a change in price will result in a proportionally equal change in the quantity demanded.

PED = % change in quantity / % change in price = {(15 - 20) / [(15 + 20)/2]} / {($4 - $3) / [($4 + $3)/2]} = -0.2857 / 0.2857 = -1 or |1| in absolute terms

Economists working for the United States have determined that the elasticity of demand for gasoline is 0.5.

INELASTIC DEMAND ⇒ when the price elasticity of demand is inelastic, a change in price will result in a proportionally lower change in the quantity demanded.

CapCityMetro decides to increase bus fare rates from $2.00 to $2.21. Consequently, the number of passengers who decide to take the bus in Austin drops from an average of 70,000 riders a day to an average of 61,000 riders a day.

ELASTIC DEMAND ⇒ when the demand for a good is elastic, a change in price will result in a proportionally higher change in quantity demanded.

PED = % change in quantity / % change in price = {(61,000 - 70,000) / [(61,000 + 70,000)/2]} / {($2.21 - $2) / [($2.21 + $2)/2]} = -0.1374 / 0.1 = -1.374 or |1.374| in absolute terms
