Answer:
A) Marginal private cost= 50
B) Total Marginal social cost to society = 70
Explanation:
A) In order to find the marginal private cost we will use the firms production cost formula as it is the private cost that the firm is enduring and is only relevant to the firm's cost and not the society's cost.
In order to find the marginal unit cost of the 10th unit produced will will replace Q in the formula by 10 as it represents quantity.
MC= 10 + 4Q
MC= 10 + 4(10)
MC= 10 +40 = 50
B) In order to find the marginal cost to society we will add the marginal external cost of the 10th unit to its private cost. We already know the marginal private cost is 50 now we need to find the marginal external cost to it to find the total marginal cost.
Marginal external cost = 2Q
Q= 10
Marginal external cost = 2*10 =20
The total Marginal cost to society= 50 + 20= 70
I believe the correct answer is D. Don’t hate me if I’m wrong
Answer:
there are 59 nickels, 12 quarters, and 213 dimes
Explanation:
- let n = nickels
- let q = quarters
- let d = dimes
first step:
d = 3 (n + q) = 3n + 3q
d + n + q = 284
0.10d + 0.05n + 0.25q = 27.25
second step:
3n + 3q + n + q = 284
0.10 (3n + 3q) + 0.5n + 0.25q = 27.25
third step:
4n + 4q = 284
0.3n + 0.3q + 0.05n + 0.25q = 27.25
fourth step:
n + q = 71
0.35n + 0.55q = 27.25
fifth step:
replace q = 71 - n
0.35n + 0.55(71 - n) = 27.25
sixth step:
0.35n + 39.05 - 0.55n = 27.25
seventh step:
11.8 = 0.2n
eighth step:
n = 59
q = 71 - 59 = 12
d = 284 - n - q = 284 - 59 - 12 = 213
Answer: demand decreases and supply stays the same
Explanation:
The equilibrium price refers to the price whereby the quantity of goods that's demanded and the quantity of goods that's supplied is equal.
On the other hand, the equilibrium quantity is gotten when the quantity of goods demanded and supplied are equal. This is gotten when the demand curve and the supply curve intersects.
It should be noted that there will be a lower equilibrium price and quantity if
In a situation whereby the demand increases and the supply remains the same, the equilibrium quantity and the equilibrium price will increase and vice versa.
Answer: Macro, External
Explanation:
Macroeconomics effect the entire world, while it scrutinizes the external forces that affect the company.
