On her 30th birthday, ann marie opened a new compound interest account with $25,000 to save for her retirement. the account pays 5% interest annually. no further deposit is made to the account and no withdrawals are made. if ann marie retires on her 60th birthday and close the account at that time, how much interest would she have earned on her initial $25,000? (round your answer to the nearest cent).

The interest in 30 years be 8305000 cent.

Step-by-step explanation:

Formula

Where P is the principle , r is the rate of interest in the decimal form and t is the time.

As given

On her 30th birthday, Ann Marie opened a new compound interest account with $25,000.

The account pays 5% interest annually.

If Ann Marie retires on her 60th birthday and close the account at that time .

P = $25000

5% is written in the decimal form.

= 0.05

r = 0.05

As  Ann Marie open account on his 30 th birthday and close it at its 60 th birthday .

Thus

t = 60 - 30

t = 30 years

Put all the value in the formula

As

Amount = Principle + Interest

Putting the value

$108050 = $25000+ Interest

$108050 - $25000 = Interest

Interest = $83050

As 1 dollar = 100 cent

Convert $83050 convert into cent .

$83050 = 83050 × 100

             = 8305000 cent.

Therefore the interest in 30 years be 8305000 cent.

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
