Find the price elasticity of demand. Is the demand elastic, inelastic, or unit? Explain your answer.

Will this product have an easy or hard to find substitute? Why?

2. The quantity demanded by product A increases 8% when the price of product B increases 16% and the other variables remain the same.

Calculate the cross elasticity of demand. Products A and B, are they complementary or substitutes? Why?

By designing a computer graph, show the change in the demand curve for product A as a result of the change in the price of product B.

3. Could it be possible that for a particular product the demand curve is perfectly inelastic, regardless of price? Explain your answer in detail.

These products, are they complementary or are they substitutes? Explain your answer.
