Unlike credit card purchases, interest charged on cash advances is already incurred even if you pay before the due date.

32% is the annual interest rate
1 month is the term
200 is the principal

32% / 12 months = 2.67% per month

200 * 2.67% = 5.34 monthly interest

200 * 32% = 64 annual interest
64/12 = 5.33 monthly interest

What if X if [ -1 -2 4 8] +X= [-5 -1 2 1]?

Arada [10]

Answer:

[-4 1 -2 - 7]

Step-by-step explanation:

[-1 - 2 4 8] + X = [-5 - 1 2 1]

X= [-5 - 1 2 1]- [-1 - 2 4 8]

X=[-5-(-1) - 1-(-2) 2-4 1-8]

X=[-4 1 - 2 - 7]

Using compound interest and a graphing calculator, it is found that it will take about 15 years for the loan to be paid off.

<h3>What is compound interest?</h3>

The amount of money earned, in compound interest, after t years, is given by:

$A(t) = P\left(1 + \frac{r}{n}\right)^{nt}$

In which:

A(t) is the amount of money after t years.

P is the principal(the initial sum of money).

r is the interest rate(as a decimal value).

n is the number of times that interest is compounded per year.

For this problem, the parameters are given as follows:

A(0) = 95000, r = 0.06, n = 12.

Hence the value of the loan after t years is:

$A(t) = P\left(1 + \frac{r}{n}\right)^{nt}$

$A(t) = 95000\left(1 + \frac{0.06}{12}\right)^{12t}$

$A(t) = 95000(1.005)^{12t}$

You have monthly payments of $1,200, hence the amount paid after t years is:

P(t) = 12 x 1,200t = 14400t

Then we have to solve for:

A(t) = P(t)

$14400t = 95000(1.005)^{12t}$

Which is solved in the graph below, meaning that it will take about 15 years for the loan to be paid off.
