Suppose you want to have $300,000 for retirement in 25 years. Your account earns 8% interest. How much would you need to deposit

Rus_ich [418]

Using the future value formula, it is found that you would need to deposit $272.95 in the account each month.

<h3>What is the future value formula?</h3>

It is given by:

$V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right]$

In which:

P is the payment.

n is the number of payments.

r is the interest rate.

For this problem, considering that there are monthly compoundings, the parameters are:

r = 0.08/12 = 0.0067, V(n) = 300000, n = 25 x 12 = 300.

Hence we solve for P to find the monthly payment.

$V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right]$

$300000 = P\left[\frac{(1.0067)^{299}}{0.0067}\right]$

1099.12P = 300000

P = 300000/1099.12

P = $272.95.

You would need to deposit $272.95 in the account each month.

On an architect's blueprint, 1 inch corresponds to 8 feet. Find the length of a wall represented by a line 1 1/8 inches long on

Keith_Richards [23]

The problem is simply asking as to convert the measurement from the smaller scale to the actual scale. For this, we simply multiply the factor to the smaller measurement. We do as follows:

Length = 1 1/8 x 8 = 9 ft

Hope this helps.
