Find the amount necessary to fund the given with drawls. Quarterly withdrawals of $850 for 9 years with an interest rate of 4.4%

Lostsunrise [7]

Answer:

The principal amount necessary to fund is $573.31

Step-by-step explanation:

Given as :

The quarterly withdrawal amount = A = $850

The time period for withdrawals = t = 9 years

The rate of interest = r = 4.4% compounded quarterly

Let The principal amount necessary to fund = $p

Now, From Compound Interest

Amount = Principal × $(1+\frac{rate}{100\times 4})^{4\times time}$

Or, $850 = p × $(1+\frac{r}{100\times 4})^{4\times t}$

Or, $850 = p × $(1+\frac{4.4}{100\times 4})^{4\times 9}$

Or, $850 = p × $(1.011)^{36}$

Or, $850 = p × 1.4826

∴ p = $\frac{850}{1.4826}$

i.e p = $573.31

So,The principal amount necessary to fund = p = $573.31

Hence, The principal amount necessary to fund is $573.31 Answer

The first three steps of completing the square to solve the quadratic equation x^2 + 4x - 6 = 0, are shown below.

SpyIntel [72]

The first three steps of completing the square to solve the quadratic equation x^2 + 4x - 6 = 0, are shown below.

step 1: x^2 + 4x = 6
step 2: x^2 + 4x + 4 = 6 + 4
step 3: (x + 2)^2 = 10
step 4: x + 2 = +/-sqrt(10)
step 5: x = sqrt(10) - 2, or x = -sqrt(10) - 2

so the steps are in order.
