Answer:
option D "The demand is unitary elastic."
Explanation:
Data provided:
At price, P1 = 3,000 units
Demand, D1 = $ 50
also,
at price P2 = $ 60
Demand, D2 = 2,500 units
Now,
the percentage change in price = 
or
the percentage change in price = 20%
and,
The percentage change in the quantity = 
or
The percentage change in the quantity = -20%
The elasticity in demand (Ed) is given as:
Ed = (Percentage change in quantity) / (Percentage change in price)
on substituting the values, we get
Ed = (-20%) / 20%
or
Ed = - 1
Here the negative sign depicts the inverse relation between the price and the demand.
hence, the correct answer is option D "The demand is unitary elastic."
<span>The opportunity cost is $8 for buying the dozen donuts. Even though the prices are the same, there is still the cost of the foregone entertainment that will not be enjoyed because of the purchase of the donuts. Had the donuts not been purchased, one would have gone to see the movie, and now this will not happen due to the donut purchase.</span>
