Suppose that a loan of $9000 is given at an interest rate of 14% compounded each year. Assume that no payments are made on the loan. Follow the instructions below. Do not do any rounding.

(a) Find the amount owed at the end of 1 year.
(b) Find the amount owed at the end of 2 years.



Answer :

Sure! Let's go through the steps to find the amount owed at the end of 1 year and 2 years for the given loan.

### Part (a): Amount Owed at the End of 1 Year

First, let's calculate the amount owed at the end of 1 year. The initial loan amount is [tex]$9000 and the interest rate is 14% per year. Step-by-Step: 1. Convert the interest rate into a decimal form: \( 14\% = 0.14 \) 2. Use the formula for compound interest to find the amount after 1 year: \[ \text{Amount} = \text{Principal} \times (1 + \text{Interest Rate}) \] 3. Plug in the values: \[ \text{Amount}_{\text{year 1}} = 9000 \times (1 + 0.14) \] 4. Calculate: \[ \text{Amount}_{\text{year 1}} = 9000 \times 1.14 = 10260 \] So, the amount owed at the end of 1 year is $[/tex]10,260.

### Part (b): Amount Owed at the End of 2 Years

Next, we need to find the amount owed at the end of 2 years. The amount accrued at the end of 1 year is [tex]$10,260 and we will apply the same 14% interest rate for the second year. Step-by-Step: 1. Use the amount from the end of 1 year as the principal for the second year: $[/tex]10,260.
2. Apply the same compound interest formula:
[tex]\[ \text{Amount} = \text{Principal} \times (1 + \text{Interest Rate}) \][/tex]
3. Plug in the values:
[tex]\[ \text{Amount}_{\text{year 2}} = 10260 \times (1 + 0.14) \][/tex]
4. Calculate:
[tex]\[ \text{Amount}_{\text{year 2}} = 10260 \times 1.14 = 11696.40 \][/tex]

So, the amount owed at the end of 2 years is [tex]$11,696.40. In summary: - The amount owed at the end of 1 year is $[/tex]10,260.
- The amount owed at the end of 2 years is $11,696.40.
