Answer to Question #200748 in Microeconomics for Nina

Question

A store that sells rice discovers that when the price of 1kg rice Is R24 per kilogram, the quantity demanded is 306 kgs per week. When the price decreases to R21 per kg, then the sales increase to 340 kgs per week. Use this information to answer questions 1 and 2 below.

1-Determine the price elasticity of rice using the Arc method.

.2Discussthe relationship between the price elasticity of rice and the total revenue the store received from the sales. Advise the store on an appropriate pricing strategy.

Answer 1

$Arc_{(Ed)}=\frac{\frac{Q_2-Q_1}{(Q_2+Q_1)\div2}}{\frac{P_2-P_1}{(P_2+P_1)\div2}}$

$=\frac{\frac{340-306}{(340+306)\div2}}{\frac{21-24}{(21+24)\div2}}$

$=\frac{34}{23}\div\frac{3}{22.5}$

$=-0.789$

2)

The price elasticity of demand is inelastic meaning an increase in price will lead to a decrease in total revenue. The a appropriate pricing stategy willl be competitive pricing strategy whereby price setting is based on what the competition charges. For example charging low price will increase the total revenue.
