Expert's answer

a) Cross price elasticity of demand refers to the percentage change in the

quantity demanded of a given product due to the percentage change in

the price of another "related" product.

b) The formula for cross-price elasticity is E c = ((P A 1 +P A 2 )/(Q 1 B +Q 2 B ))*((Q 2 B -Q 1 B )/ /(P A 2 -

P A 1 )).

c) E c = (($1000+$900)/(40+20))*((20-40)/($900- $1000))= 6,33

d) With a well-run advertising company, the sales of apples have skyrocketed, and

the number of oranges sold will decrease, so cross-elasticity will decrease.

e) E c = (($40+$20)/(40000+10000))*((10000-40000)/($20- $40)) = 1,8.
