Answer:
a. 2.20
Explanation:
The computation of the price elasticity of supply is shown below;
Here,
P1 = $1 Q1 = 100
P2 = $1.20 Q2 = 150
We know that
Price elasticity = percentage change in quantity supplied ÷ percentage change in price
where
Percentage change in quantity supplied = (Q2-Q1)÷(Q2+Q1) ÷ 2)×100
= (150-100) ÷(150+100) ÷ 2)×100
= 40
And,
Percentage change in price is
= (P2-P1) ÷ (P2+P1) ÷ 2)×100
= ($1.20 - $1) ÷ ($1.20 + $1) ÷ 2)×100
= 18.1818
So, price elasticity of supply is
= 40 ÷ 18.1818
= 2.20
At a price of $1.00, a local coffee shop is willing to supply 100 cinnamon rolls per day. At a price of $1.20, the coffee shop would be willing to supply 150 cinnamon rolls per day. Using the midpoint method, the price elasticity of supply is about:______.
B. 0.90
C. 1.11
D. 0.45
