Answer:
total revenue for 500 is $2500
total revenue for 400 is $2800
Explanation:
given data
price of good A = $50
quantity demanded of good A = 500 units
price of good A rises = $70
quantity demanded of good A falls = 400 units
solution
we get here Elasticity of demand that is express as
Elasticity of demand = (change in quantity ÷ average quantity) ÷ (change in price ÷ average price) .......................1
here
Change in quantity is = 400 - 500 = -100
and average quantity is =
= 450
and change in price is = 70 - 50 = 20
average price is =
= 60
so now we put all value in equation 1
Elasticity of demand = ![\frac{\frac{-100}{450} }{\frac{20}{60} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B-100%7D%7B450%7D%20%7D%7B%5Cfrac%7B20%7D%7B60%7D%20%7D)
Elasticity of demand = -0.67
as here the elasticity of demand is inelastic because elasticity is above -1
so about total revenue when price will increases as elasticity is inelastic
so increase in price will cause increase in revenue because revenue is maximum when elasticity = -1
and increase in price will cause increases elasticity in the absolute term and revenue will increase
total revenue = price × quantity
so
total revenue for 500 = 500 × 5 = $2500
total revenue for 400 = 400 × 7 = $2800
