Expert's answer

Elasticity of demand refers to the responsive change of quantity demanded as a result of changes in factors affecting the demand. One of the factor that influence the demand is the price.

The Price elasticity of demand is calculated using the following formula:

"\\text{Arc price elasticity of demand}=\\dfrac{\\Delta Q}{\\Delta P}*\\dfrac{\\bar{P}}{\\bar {Q} }"

"\\bar{P} \\bar {Q}" are the price and the Quantity mid point.

"\\text{Arc price elasticity of demand}=\\dfrac{360-300}{108-120}*\\dfrac{ \\dfrac{120+108}{2}}{\\dfrac{360+300}{2}}"

"\\text{Arc price elasticity of demand}=\\dfrac{60}{-12}* \\dfrac{114}{330}"

"\\text{Arc price elasticity of demand}=-1.73"

Therefore, since the elasticity is more than 1 in absolute terms, then we can conclude that the type of elasticity is elastic in nature.
