Answer:

PED = -0.67 or |0.67| in absolute terms, price inelastic

Explanation:

price elasticity of demand = percentage change in quantity demanded / percentage change in price

percentage change in quantity demanded = (110 - 90) / 90 = 22.22%

percentage change in price = ($0.80 - $1.20) / $1.20 = -33.33%

PED = 22.22% / -33.33% = -0.67 or |0.67| in absolute terms, price inelastic
