You deposit $400 each month into an account earning 8% interest compounded monthly. Round to the nearest cent as needed. a) How
Debora [2.8K]

If I deposit $400 each month into an account earning 8% interest compounded monthly, I will have $6,517 in my account in 35 years. The total money that I will put into the account is $168,000. I will earn a total compound interest of $6,117.

  • Calculating the Sum of Money in 35 years

Given information is as follows,

Principal, P = $400

Rate = 8%

Time, T = 35 years

n = 12 (Compounded monthly)

The amount for compound interest is given as,

A = P\frac{(1+\frac{R}{n} )^{nT} -1}{R/n}

A = 400\frac{(1+\frac{0.08}{12} )^{12.35} -1}{0.08/12}

A = 6,517.02

A = $6,517 (to the nearest cents)

  • Calculating the Amount Put in Account

Since, $400 is deposited every month for 35 years,

Amount Put in 35 years for this compound interest =$400 × 12 × 35

= $168,000

  • Calculating the Compound Interest

A = P + CI

Thus, the compound interest is given by,

CI = A - P

CI = 6517 - 400

CI = $6,117

I will earn a total interest of $6,117

An open box is to be made from a square piece of cardboard, 18 inches by 18 inches, by removing a small square from each corner
seraphim [82]

The dimension of the box of the greatest volume that can be constructed in this way is 12x12x3 and the volume is 432.

<h3>How to solve the dimension?</h3>

Let x be the side of the square to remove. Then the volume of the box is:

V(x) = (18 - 2x)² * x = 324x - 72x² + 4x³

To find the maximum volume, differentiate and set it to 0:

V'(x) = 324 - 144x + 12x²

0 = x² - 12x + 27

0 = (x - 9)(x - 3)

x = 3 or 9

When x = 3,

V"(x) =-144+24x

V"(3) =-144+72=-72<0

so volume is maximum at x=3

Therefore the box is 12x12x3 and the volume is 432.

3x+1/5y=7 solve for y
Vladimir79 [104]
Hello!

First, let's write the problem.
3x+\frac{1}{5}y=7
Subtract 3x from both sides.
3x+\frac{1}{5}y-3x=7-3x
\frac{1}{5}y=7-3x
The opposite of division is multiplication, so we are going to multiply in order to undo the fraction.
5\cdot \frac{1}{5}y=5\cdot \:7-5\cdot \:3x

Our final answer would be, 
y=35-15x

Thanks!
