Suppose that you deposit $4,500 in your bank and the required reserve ratio is 18 percent. The maximum loan your bank can make as a direct result of your deposit is 3690.
<h3>
What exactly is a bank loan and the required reserve ratio?</h3>
- A loan is a quantity of money that one or more people or businesses obtain from banks or other financial organizations in order to handle their finances in connection with anticipated or unforeseen circumstances.
- By doing this, the borrower creates a debt that must be repaid with interest within a predetermined time frame.
- The percentage of deposits that authorities mandate a bank maintain in reserves and refrain from lending out is known as the required reserve ratio.
- If the required reserve ratio is 1 to 10, a bank can only lend out $0.90 of every dollar it has on deposit, but it must retain $0.10 in reserves.
Hence, The maximum loan your bank can make as a direct result of your deposit is 3690.

Answer:

Explanation:
We want to know the value of
when 

From here, we can find the factors of the quadratic equation, we need two numbers that multiplied give -400 and added -30. Since they are factors of 400, we can choose -20x20 or -40x10. When adding -20 and 20 the result is zero, but the sum of -40 and 10 is -30. Then:

The solutions of the quadratic equation are
and
:

Since
is a positive integer:

In this item, we calculate first for the price of each can of coffee by dividing the cost by the number of cans of coffee.
Price per can = cost / total number of cans of coffee
price per can = ($2.40) / 4 = $0.6/can
To compute for the price of the 1/4 can, multiply the price by can by 1/4.
price of 1/4 can of coffee = (1/4 can)($0.6/can)
price of 1/4 can of coffee= $0.15
Therefore, the 1/4 can of coffee will cost only $0.15.
