The high school student should analyze the point at which the marginal cost equals the marginal benefit.
In other words, he or she should see if the increased costs of attending Petesburg University are more or less equal to the increased benefit that is gained from graduating from a more prestigious university.
The student should also analyze the possible opportunity cost in the future. Attending amore renowned college can result in better job prospects than doing otherwise. Higher salaries in the future could be given up if he or she chooses the cheaper option.
In order to buy a car worth $25,000 a monthly payment of $622.12 is required.
Mortgages are one type of loan that frequently has a structure that calls for a stream of identical monthly payments. The lender can assess whether the customer's budget can support equal monthly payments by doing so.
Suppose the monthly payment is M.
With 9 percent APR, the effective monthly rate is 9%/12 = 0.75%.
There will be 12 x 4 years, or 48 monthly payments.
The face value of the loan must be equal to the present value of these monthly payments, or

which yields M = 622.12.
If you only paid interest, the monthly payment would be calculated as follows: principal * monthly interest rate (9% /12) = 25,000*0.75% = 187.5.
The results would be that after five years, you would still owe the whole amount of $25,000 and would have to pay $11,250 in interest.

Explanation:
To find dead weight loss we will take into consideration the price and output level of both monopoly and perfect competition.
Dead weight loss = {(P2 - P1) * (Q1-Q2)} / 2
Where, P2 and Q2 are price and quantity respectively of monopolist and P1 and Q1 are price and quantity respectively of perfect competiton.
Dead weight loss = {(130-40) * (60-30)}/2
= (90*30)/2
= $1350
