The fall in price leads to rise in total revenue and this means the demand is elastic.
How to illustrate the information?
Price of widgets= $8
Total revenue= P*Q= 8*12= $96
Price= $7
Total revenue= 7*16= $112
Fall in price leads to rise in total revenue, it means demand is elastic.
b. Price = $7 maximizes the total revenue. Total revenue when price=$7, total revenue = Price* quantity
= $7 × 16=$112.
c. When the price is equal to $9, the demand is elastic. Therefore, there should be a decrease in price in order to increase total revenue.
d. Price elasticity of demand= ((96-112)/(112+96)/2)) ÷((8-7)/(8+7)/2))
= -2.14
This is an elastic demand.
e. When price=$6, Quantity=18
When Price=$5, Quantity= 20
Price elasticity of demand= ((20-18)/(20+18)/2)) ÷((5-6)/(5+6)/2))
= - 0.58
This is an inelastic demand.
f. Total revenue falls from $108 to $100 when the price falls from $6 to $5.
