Final answer:

To have $10,000 in ten years with an interest rate of 10% compounded annually, you would need to deposit approximately $3,854.84 in the bank account.

Step-by-step explanation:

To find out how much money you need to deposit now in order to have $10,000 in ten years with an interest rate of 10% compounded annually, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

  • A is the future value (amount of money you want to have)
  • P is the principal (the initial amount of money you deposit)
  • r is the interest rate (expressed as a decimal)
  • n is the number of times the interest is compounded per year
  • t is the number of years

Plugging in the given values, we have:

10,000 = P(1 + 0.10/1)^(1 × 10)

Simplifying, we get:

10 = P(1.10^10)

Dividing both sides by 1.10^10, we get:

$10,000 / 1.10^10 = P

Calculating using a calculator, we find that P is approximately $3,854.84. Therefore, you would need to deposit $3,854.84 in the bank account to have $10,000 in ten years.
