Using the Midpoint method compute the elasticity in the following cases and explain your answers.

  

Price

Quantity Demanded

(Income = AED60,000)

Quantity Demanded

(Income = AED90,000)

50

2000

1500

75

1500

1000

1. Calculate the income elasticity of demand when income rises from AED 60,000 to AED90,000 at a price of AED 75. (1 Mark)

2. Due to COVID 19, the average price of a Jones the Grocer meal fell from AED100 to

AED 80. As a result, Slim’s quantity demanded for Jones the Grocer meals increased from 2 to 3 times per week. What would be the implied price demand elasticity? (1 Mark)

3.Last week, sellers of good B took in AED500 in total revenue on sales of 200 units of good B. This week they raised the price of B price and took in AED800 in total revenue on sales of 200 units. At the same time, the price of good A stayed the same, but sales of good A increased from 1000 units to 1600 units. Compute the cross-price elasticity between A and B. (1 Mark)
