Select the correct answer.

Walter took out a [tex] \$6,000 [/tex] loan for six years. He is being charged 6 percent interest, compounded annually. Calculate the total amount he will pay.

Total amount [tex] = P (1 + r)^{t} [/tex]

A. [tex] \$7,657.69 [/tex]
B. [tex] \$8,040.57 [/tex]
C. [tex] \$8,511.12 [/tex]



Answer :

To calculate the total amount Walter will pay for his [tex]$\$[/tex] 6,000[tex]$ loan over six years with an annual interest rate of 6%, compounded annually, we will use the compound interest formula: \[ A = P \left(1 + \frac{r}{n}\right)^{nt} \] Here, - \( P \) is the principal amount (initial amount of the loan), which is \$[/tex]6,000.
- [tex]\( r \)[/tex] is the annual interest rate, which is 6% or 0.06.
- [tex]\( n \)[/tex] is the number of times the interest is compounded per year, which in this case is 1 (annually).
- [tex]\( t \)[/tex] is the number of years the money is invested or borrowed for, which is 6 years.

Using these values, the formula simplifies to:

[tex]\[ A = 6000 \left(1 + 0.06\right)^6 \][/tex]

First, we calculate the growth factor:

[tex]\[ 1 + 0.06 = 1.06 \][/tex]

Next, we raise this growth factor to the power of 6:

[tex]\[ 1.06^6 = 1.4185 \][/tex]

Now we multiply the principal by this value:

[tex]\[ A = 6000 \times 1.4185 = 8511.12 \][/tex]

Therefore, the correct total amount Walter will pay after six years is:

[tex]\[ \boxed{8511.12} \][/tex]

Thus, the correct answer is:
C. [tex]$\$[/tex] 8511.12$
