Answer:price elasticity of demand for Dunkin Donuts’ regular coffee is 1.8

Explanation: Using the midpoint formnulae

Price elasticity of Demand =percentage change in quantity demanded/ Percentage change in price.

Percentage change in quantity = new quantity - old quantity / (new quantity + old quantity)/2 x 100

= 40-10/(40+10)/ 2 = 30 /25 = 1.2 x 100 =120%

Percentage change in price = new price - old price / new price + old price)/2 x 100

= 1- 2 / (1+2)/2= -1/1.5x 100 = -66.67 %

Price elasticity of Demand =percentage change in quantity demanded/ Percentage change in price.

= 120%/-66.67%= -1.79 = -1.8

For Price elasticity of demand, the sign is not included and the basis for elasticity is on the value itself . here we can conclude that the Price elasticity of demand for Dunkin donut is 1.8 and elastic because a fall in price led to an increase in amount being sold.
