Answer:

Explanation:
this problem can be solved applying the concept of annuity, keep in mind that an annuity is a formula which allows you to calculate the future value of future payments affected by an interest rate.by definition the future value of an annuity is given by:

where
is the future value of the annuity,
is the interest rate for every period payment, n is the number of payments, and P is the regular amount paid
But there is an special thing to keep in mind and is the initial payment so we must to calculate the 4,000 in the future so we have:



Answer:
c. cash, checking account balances, and travelers' checks.
Explanation:
Money Supply is the concept that means the amount of the liquid financial products and total currency in the market or economy. It is regulated the macro-economically by the monetary policy. So, there are types of measures of money supply or stock:
-M0: narrowly, it means the hard currency in circulation
-MB: it equals M0+ the hard currency which are not technically in circulation and in bank reserves.
-M1: it is the most common one and equals M0 plus checking accounts plus travelers’ checks and other checkable deposits.
-M2: covers M1 and saving accounts and CDs.
-M3: it surrounds the larger deposits.
-MZM: finally, this indicates the money market deposits.
That’s why we could notice that M1 narrowly means the cash, checking account and travelers’ checks.
Expand the equation.
Multiply (distribute) the first numbers of each set, outer numbers of each set, inner numbers of each set, and the last numbers of each set.
Combine like terms.
Solve the equation and simplify, if needed.
Divide the numbers on the first graph by 1’s and you get your answer
