At age 23​, someone sets up an IRA​ (individual retirement​ account) with an APR of ​7%. At the end of each month he deposits ​$
MAVERICK [17]

Answer:

The ira will contain $228,278.05 when he retires at age 65. This is 6.04 times the amount of money he deposited.

Step-by-step explanation:

In order to solve this problem, we can make use of the following formula:

FV=PMT[\frac{(1+i)^{n}-1}{i}]

Where:

FV= Future value of the ira

PMT= the amount of money you deposit each month

i= is the interest rate per period

n=number of periods

in this case we will assume the interest will be compounded each month.

So:

FV this is what we need to know.

PMT= $75  the amount he will deposit each month

t = 42 years,

this is 65-23=42

n=42 years * 12 months/year = 504 months

i=0.07/12

So we can now use the given formula:

FV=PMT[\frac{(1+i)^{n}-1}{i}]

FV=75[\frac{(1+\frac{0.07}{12})^{504}-1}{\frac{0.07}{12}}]

So we get:

FV=$228,278.05

which is the amount of money he will have after 42 years.

In total, he deposited:

$75*504months = $37,800

so he will have:

\frac{228,278.05}{37,800}=6.04 times the amount of money he deposited throughout this time.

If f(x) = |2x - 4|, find f(-7)
Digiron [165]

hey there!!

Given :

f ( x ) = l 2x - 4 l , find f ( - 7 )

We will have to substitute the value of -7 instead of x

f ( -7 )  = l -14 - 4 l

f ( -7 ) = l -18 l

As the value in a mod shall always be positive, the answer would become 18

Hence, the required answer is 18

Hope my answer helps!!
