Answer: The marginal benefit of $2500 is greater than the marginal cost of $1700 for the new waitress.
In economics, a rational decision is a decision where the total benefit equals or exceeds the costs associated with that decision.
In this case, Carroll's diner pays the new waitress $1700, but is able to earn $2500 by serving customers more quickly. Since the diner earns $800 (2500 -1700) more than the cost paid to the waitress, we can say that hiring an additional waitress is a rational economic decision.
Answer:
= 32.7%
Explanation:
<em>Return on a stock is the sum of the dividends and the capital gains.</em>
<em>Capital gains = Sales value of stock - Cost of investment</em>
= (158.29 -150.68 )× 100
= 761
Dividends = 4.69 ×100
=469
Cost of investment =150.68 ×100
Return in %
= Total return / cost of stocks ×100
=(761 + 469)/ (150.68 ×100 ) ×100
=8.2% for 3 months
Annualized return
=( 8.2 %/3 ) × 12
= 32.7%
Annualized return= 32.7%

The marginal revenue of the 11th unit would be $10. Option A is correct.
<h3>What is the marginal revenue?</h3>
The increase in income that occurs from the sale of one more unit of production is referred to as marginal revenue. While marginal income can remain constant over a given amount of output, the law of diminishing returns dictates that it will ultimately slow down as output level grows.
<u>Formula</u>:
.........................................(1)
Where,
n = Output Produced.
MR = Marginal Revenue
TR = Total Revenue
Computation of marginal revenue of the 11th units:
It is assumed that the company can sell 10 units for $21 each. As a result, the total income from the sale of ten units is $210. However, if the price is reduced to $20, it may sell 11 units. As a result, the total income generated from the sale of 11 units is $220.
By applying the values in formula (1),
$220 – $210 = $10.
Therefore, option A is correct.
