maxonik [38]

Using the monthly payment formula, it is found that the balance of the plan is of $26,731.23.

<h3>What is the monthly payment formula?</h3>

It is given by:

$A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}$

In which:

A is the monthly payment.

P is the total amount.

r is the interest rate.

n is the number of payments.

The parameters for this problem are given as follows:

A = 144, r = 0.06, n = (68 - 24) x 12 = 528.

Then:

r/12 = 0.06/12 = 0.005.

$A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}$

$144 = P\frac{0.005(1 + 0.005)^{528}}{(1 + 0.005)^{528} - 1}$

$P = 144\frac{(1 + 0.005)^{528} - 1}{0.005(1 + 0.005)^{528}}$

P = $26,731.23.

Anna007 [38]

F(x) = 2w + I = 2w 5000/w

f'(x) = 2 - 5000 / w^2

Fencing is minimum, so f(x) = 0

2 - 5000/w^2 = 0

2 = 5000 /w^2

2w^2 = 5000

w = 50

I = 5000/2

= 1000

2w + I
= 200
