Answer:
-0.33
Explanation:
The calculation of the price elasticity of demand using mid point formula is shown below:
= (change in quantity demanded ÷ average of quantity demanded) ÷ (percentage change in price ÷ average of price)
where,
Change in quantity demanded is
= Q2 - Q1
= 80 units - 100 units
= -20 units
And, the average of quantity demanded would be
= (80 units + 100 units) ÷ 2
= 90 units
Change in price is
= P2 - P1
= $2 - $1
= 1
And, the average of the price is
= ($2 + $1) ÷ 2
= 1.5
So, after solving this, the price elasticity of demand is -0.33

Answer: A.
Explanation:
By definition, opportunity cost is the amount or value of something you gave up for another good.
For example: say you value sleeping in at $5 value going to class at $4. You decide to get up and go to class, the $4 value. Therefore, your opportunity cost is what you gave up (sleeping in) for another good/choice (going to class), is $5 since you valued sleeping in at that.
