Computing the Price Elasticity of Demand:

[Md. Alamgir Hossan]

The price elasticity of demand is computed as the percentage change in the quantity demanded divided by the percentage change in price.

"Price\ elasticity\ of\ demand"="Percentage\ change\ in\ quatity\ demanded" /"Percentage\ change\ in\ price"
"Price\ Elasticity\ of\ Demand\="  ((Q_2-Q_1  )⁄[(Q_2+Q_1)"\/\2"])/((P_2-P_1  )⁄[(P_2+P_1)"\/\2"])

Computing the Price Elasticity of Demand

█(E_D=(("\1\0\0\-\5\0")("\1\0\0"+"\5\0")"\/\2")/((4"\.\0\0\-\5\.\0\0")(4"\.\0\0"+5"\.\0\0")"\/\2" )@@="\6\7\ percent" /"\-\2\2\ percent" ="\-\3"@|-3|@3@)

Demand is perfectly elastic.
