#### Homework Answers

Answer #1

Cross elasticity of demand measure the degree of responsiveness of quantity demanded of one related good to a change in the price of another related good.
Cross elasticity = %change in quantity demanded of one related good / %change in the price of another related good.

In the question,

% Increase in the price of skateboard is 4% and

% Decrease in the quantity demanded elbow pads is 1%

Cross Elasticity = -1% / 4%

Cross Elasticity = -0.25

As the cross elasticity is negative, the goods are complementary.
