A person invests 1000 dollars in a bank. The bank pays 4% interest compounded quarterly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 1600 dollars?

The amount is $8358.7 and the interest is $3858.7.

Step-by-step explination

STEP 1: To find amount we use formula:

A = P

1 +

r

n

n·t

A = total amount P = principal or amount of money deposited, r = annual interest rate n

= number of times compounded per year t = time in years In this example we have

P = $4500 , r = 7% , n = 2 and t = 9 years

After plugging the given information we have

A = 4500

1 +

0.07

2

2·9

A = 4500 · 1.03518

A = 4500 · 1.857489

A = 8358.7

STEP 2: To find interest we use formula A = P + I, since A = $8358.7 and P = $4500 we

have:

A = P + I

8358.7 = 4500 + I

I = 8358.7 − 4500

I = 3858.7

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
