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.

How to solve (((1/y-1)+(5/12))=(-2/3y-3))

TEA [102]

(((1/y - 1) + (5/12)) = (-2/3y - 3))
((((1)(12)/12(y - 1) + (5(y + 1)/12(y + 1) = (-2/3y - 3))
((12/12y - 12) + (5y + 5/12y - 12)) = (-2/3y - 3))
((5y + 17/12y - 12) = (-2/3y - 3)
(12y - 12/5 + 17) × (5y + 17/12y - 12) = (-2/3y - 3)(12y - 2/5 + 17)
y = -21y + 4/66y - 66
y = -7/22 - 2/33
y = -25/66

A train left for London, and after 9 hours later, a car traveling 80 miles per hour tried catching up to the train. After 3 hour

morpeh [17]

Answer:

20 miles per hour

Step-by-step explanation:

Given that the train left for London, and after 9 hours later, a car traveling 80 miles per hour tried catching up to the train. After 3 hours, the car caught up

Which means that the car travelled the same distance in 3 hours as the train travelled in 9 + 3 = 12 hours

Let the distance be d

Given the speed of car is 80 miles per hour

We know that $speed=\frac{distance }{time}$

$80=\frac{d}{3}$

d = 240 miles

Now for the train Average speed = total distance / total time taken

Average speed of the train = $\frac{240}{12}$ = 20 miles per hour
