Answer:
It is deducted from the workers
Explanation:
All employers are required to deduct social security and medicare taxes from their employees' paychecks. The deducted amounts are remitted to the government through the social security administration authority.
Therefore, the funds for Social Security and Medicare come from the employees' paycheck. It is the workers who contribute these funds from their income.
<u>Given:</u>
Loan amount = $250000
Interest rate = 5.5%
Interest payment = $2042.71
<u>To find:</u>
Total amount of interest
<u>Solution:</u>
The total number of months in 15 years = 
Total monthly payments will be 
So, the total pay-backs will be $3,67,687.8
Total interest paid will be as follows,

On plugging-in the values in the above formula we get,

Therefore, the total amount of interest that the borrower will pay over the course of the loan is $1,17,687.80.
Answer: 16 units more than social optimum.
DWL = dead weight loss = (1/2)*(Q* - Q°) 12 =96
Explanation:
Q=1200 - 4P and Q=-240 + 2P
In a free market quantity demand =quantity supplied
1200 -4P = -240 +2P
P =240
Sub P
Q* = 240
Socially optimal quantity is
Marginal social benefit (MSC)= marginal social cost(MSC), including external damage =MEC
MPC= marginal private cost =inverse of supply function
MPC = (1/2)*Q + 120
MEC=12
MSC =(MPC +MEC) = (1/2)Q +120 +12
MSC= MPB where MPB is marginal private benefit = inverse of demand functn
MPB = 300 -(1/4)Q
(1/2)Q + 132 =300 - (1/4)Q
Q° = 224
Difference btw Q* & Q° = 16 units more than social optimum.
DWL = dead weight loss = (1/2)*(Q* - Q°) 12 =96
