1.If a 6% increase in the price of toilet paper results in a 4% reduction in the quantity demanded,

a.What is the price elasticity of demand for toilet paper?

b.Is this elastic, inelastic, or unit elastic?

2.If price elasticity of demand is 1.7, by how much will quantity demanded decrease with a 9% increase in price?

\fI The table ahnve has twn points on the demand curve for pizza from a particular pizza parlor. I The ahsnlute value efle percent change in quantity demanded is [[5011 d] + 450'] x It'll} = 22.2 percent I The absolute value nt'the percentage change in price is [{$14 $16] + $15] x l = 13.3 percent. I Between these twe paints en the demand curve. the price elasticity of demand is 22. 2'l'n 13. 3%: 1. Eli". Inelastic and Elastic Demand I If the price elasticity efdemand is less than 1.1}. the gend is said tn have an inelastic demand. In this case. the percentage change in the quantity demanded is less than the percentage change in price. sand .1 9MP = Elasticity c 1 = Inelasc I If the price elasticity cf demand is equal tn 1.0. the good is said tn _W have a unit elastic demand. In this case. the percentage change in the quantity demanded equals the percentage change in price. a Perfecy Mud = 9MP = Elasticity = 1 = Unit Elastic inelastic I If the price elasticity of demand is greater than Ll]. the gced is said have an elastic demand. In this case. the w ercenta e chan ~ e I If the quantity demanded changes by an innitely large percentage in resppnse to a tiny price change. then the good is said tn have perfectly elastic demand. The price elasticity if demand is innite and le gend's demand curve is a herizental line. Illcuu u Imam: and em Durand I If the quantity demanded changes by an innitely large percentage in response to a tiny price change, then the good is said to have pcerl'emdjglr elastic demand. The price elasticityIr of demand is innite and the good's demand curve is a horizontal line. FIGURE 4.1 Inelastic and Elastic Demand \fPrice Quantity Demanded $61 275 $63 250
