Answer:
9.50 dollars
Explanation:
The marginal revenue is the revenue generated for an additional sale.
In this case the new customer will generate an additional revenue equal to the service change to him. This amount is for 9.50 dollars. So, this is the marginal revenue for an additional sale.
The rest of the option are incorrect.
Answer:
The correct answer is: black market for apartments whereby higher rents are obtained through various other charges.
Explanation:
A price ceiling refers to an upper limit fixed for the price of a product or service. A rent ceiling means that rent cannot be charged higher than this limit.
This rent ceiling would create higher demand and a smaller supply of apartments. This is because of law of demand and law of supply.
Because of shortage of apartments in the market, a black market will be created where the apartment owners will be able to charge higher rents through other charges.
Answer: 3.22
Explanation:
Given that;
mean = 2.5 min
standard deviation = 0.25 min
now to get the value of X required, we say
z = (x - u) / a
where z is the distance from the mean measured in the standard deviation units, x is the value we are interested in, u is the mean distribution, a is the standard deviation of the distribution.
the time delay should be just enough to allow 99.8% of the cabinets to dry completely = 99.8/100 = 0.9980
first we determine an appropriate z value.
Using the standardized normal tables,
value of z for approximately 0.9980 is 2.88
so using our initial equation z = (x - u) / a
we substitute the value
z = (x - u) / a
2.88 = ( x - 2.5) / 0.25
2.88 * 0.25 = x - 2.5
0.72 = x - 2.5
x = 0.72 + 2.5
x = 3.22
