Answer 2

Calculation of the Amount in the Bank Account after N Years

To calculate the amount in the bank account after N years, we need to consider the initial amount deposited and the annual interest rate added to the account.

Let's assume that the initial amount deposited is A, and the annual interest rate is R (expressed as a decimal). The amount in the bank account after N years can be calculated using the formula:

Amount after N years = A * (1 + R)^N

Where: - A is the initial amount deposited - R is the annual interest rate - N is the number of years

Now, let's apply this formula to the given scenario.

Applying the Formula to the Given Scenario

In the given scenario, a certain amount of money is deposited in the bank, and the bank adds a predetermined percentage of the amount to the account each year.

Let's assume the initial amount deposited is A, and the annual interest rate added is P (expressed as a percentage). We need to calculate the amount in the bank account after N years.

Using the formula mentioned earlier, the amount after N years can be calculated as:

Amount after N years = A * (1 + P/100)^N

Now, let's substitute the given values into the formula and calculate the amount in the bank account after N years.

Calculation Example

Let's consider an example to illustrate the calculation.

Assume that a person deposits $1000 in the bank, and the bank adds 5% interest to the account each year. We want to calculate the amount in the bank account after 3 years.

Using the formula:

Amount after N years = A * (1 + P/100)^N

Substituting the given values:

Amount after 3 years = $1000 * (1 + 5/100)^3

Calculating the amount:

Amount after 3 years = $1000 * (1 + 0.05)^3

Amount after 3 years = $1000 * 1.05^3

Amount after 3 years ≈ $1157.63

Therefore, the amount in the bank account after 3 years would be approximately $1157.63.

Conclusion

In conclusion, to calculate the amount in the bank account after N years, we need to know the initial amount deposited and the annual interest rate added to the account. By using the formula mentioned above, we can determine the amount after N years. In the given scenario, the formula can be applied by substituting the given values to calculate the amount in the bank account after N years.
