Answer:
See explanation below
Explanation:
Here, when the price of guppy gummies increases by 5%, the quantity of raskels sold decreases by 4% and the quantity of cannes sold increases by 5%.
i.e, % change in price of guppy grummies = 5%
% change in quantity of raskels = -4%
% change in quantity of cannes = 5%
i) Find the Cross price elasticity of demand between guppy grummies and raskels. Use the expression below.
% change in quantity demanded of raskels / % change in price of guppy gummies
= -4% / 5%
= -0.8
Substitute goods have a negative cross price elasticity of demand. Since, the cross price elasticity of demamd here is negative, the goods are substitute.
It is recommended not to advertise raskels with guppy grummies
ii) Find the Cross price elasticity of demand between guppy grummies and cannes. Use the expression below.
% change in quantity demanded of cannes / % change in price of guppy gummies
= 5% / 5%
= 1
Complement goods have a positive cross price elasticity of demand. Since, the cross price elasticity of demamd here is positive, the goods complement each other.
