Elasticity Formula Deck

PED% change in quantity demanded ÷ % change in price
PES% change in quantity supplied ÷ % change in price
% change(new − original) ÷ original × 100
RevenuePrice × Quantity sold

For PED classification, focus on the size of the PED value: > 1 elastic, < 1 inelastic, = 1 unitary.
