Answer:

Example: Suppose you give $100 to a bank which pays you 10% compound interest at the end of every year. After one year you will have $100 + 10% = $110, and after two years you will have $110 + 10% = $121.

Problem:

If you deposit $4500 into an account paying 7% annual interest compounded semi anualy , how much money will be in the account after 9 years?

Result:

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

Explanation:

STEP 1: To find amount we use formula:

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

After plugging the given information we have

STEP 2: To find interest we use formula , since 8358.7  P =  we have:

3858.7

All of number one thank you

I'm going to divide number one to 6 parts
1. \frac{4}{10} = \frac{40}{100}
2. \frac{7}{10} = \frac{70}{100}
3. \frac{2}{10} = \frac{20}{100}
4. \frac{9}{10} = \frac{90}{100}
5. \frac{18}{10} = \frac{180}{100}
6. \frac{26}{10} = \frac{260}{100}

because to make the denominator to 100, you need to multiply 10 by 10 which is 100.
and because you multiply 10, you also have to multiply the numerator by 10.
EXAMPLES: \frac{3}{10} = \frac{3}{10} × \frac{10}{10} = \frac{30}{100}
