Solution

Cross elasticity of demand (XED) measures the percentage change in quantity demand for a good after the change in price of another.



Exy=Qx2Qx1Py2Py1×Py2+Py1Qx2Qx1E_{xy}=\dfrac{Q_{x2}-Q_{x1}}{P_{y2}-P_{y1}}\times\dfrac{P_{y2}+P_{y1}}{Q_{x2}-Q_{x1}}


We are given;

Qx2=6,000Q_{x2}=6,000 Qx1=5,000Q_{x1}=5,000

Py2=$12P_{y2}=\$12 Py1=$15P_{y1}=\$15


Exy=6,0005,000$12$15×$12+$156,000+5,000E_{xy}=\frac{6,000-5,000}{\$12-\$15}\times\frac{\$12+\$15}{6,000+5,000}


Exy=0.818E_{xy}=-0.818


Py2 for Qx2 of 3000P_{y2}~for ~Q_{x2} ~of ~3000 given that ExyE_{xy} does not change.


0.818=3,0005,000Py2$15×Py2+$153,000+5,000-0.818=\frac{3,000-5,000}{P_{y2}-\$15}\times\frac{P_{y2}+\$15}{3,000+5,000}


Solving for Py2P_{y2}


Py2=$28.204P_{y2}=\$28.204
