Use the following formula to answer the following equations.

Elasticity = % change in QD

% change in Price

% Change = Original Number- New Number X 100

Original Number

Find if the demand for the good using the equation then figure out if the good is elastic, inelastic, or unitary elastic.

REMEMBER: E>1 ELASTIC

E<1 INELASTIC

E=1 UNITARY ELASTIC
