The price elasticity of demand can be calculated using the following formula:
E = (% change in quantity demanded)/(% change in price)
First, let's calculate the percentage change in quantity demanded:
% change in quantity demanded = ((new quantity - old quantity) / old quantity) x 100
% change in quantity demanded = ((27,000 - 20,000) / 20,000) x 100
% change in quantity demanded = 35%
Next, let's calculate the percentage change in price:
% change in price = ((new price - old price) / old price) x 100
% change in price = ((45,000 - 50,800) / 50,800) x 100
% change in price = -10.16%
Using these values, we can calculate the price elasticity of demand:
E = (% change in quantity demanded)/(% change in price)
E = 35% / -10.16%
E = -3.44
Since the elasticity is greater than 1, we can conclude that the demand for Mercedes-Benz M-Class vehicles is price elastic, meaning that a decrease in price leads to a proportionally larger increase in quantity demanded.
