<span>The sum of all the federal deficits over time is known as the "national debt".
</span>
National debt refers to the total of all exceptional debt owed by the government. It incorporates the cash the legislature has obtained, as well as the interest it must pay on the acquired cash. The administration strays into the debt when it doesn't gather enough income to cover the costs it brings about from spending on projects, for example, the military, or building streets and extensions. The incomes originate from corporate and salary charges, and the expenses the legislature forces, for example, for visas and travel permits, student loans, and admission to national parks.
        
             
        
        
        
Answer:
The correct answer is letter "A": Screening mechanism.

The screening mechanism is the activity in which people identify good qualities in others by evaluating their actions and matching them with their own behavior so they can eventually qualify those other people as suitable for them or not.
In the example, <em>Sally must consider a good practice to give generous tips to waiters since only if Andy, her date, does such a thing, she will consider dating him again. What Sally conducted is an example of a screening mechanism.</em>

Answer:
FV= $94,108.42
Explanation:
<u>First, we need to calculate the future value of the 12 annual deposits:</u>
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {3,500*[(1.06^12) - 1]} / 0.06
FV= $59,044.79
<u>Now, the future value at the end of the 20 years (8 years more):</u>
FV= PV*(1 + i)^n
FV= 59,044.79*(1.06^8)
FV= $94,108.42
