Solution:
Given,
The equilibrium price is $5.50 (P)
The equilibrium quantity is 37.0 (Q)
The price is $ 8.75
(percentage change in quantity)/(percentage change in price)
So Motorcycles would be the following:
[(63 - 29)/29]/[($12.75 - $0.50)/$0.50]
=62 / 11.75
= 5.27
Evaluate, then do the same for pancakes.
