Final answer:

The amount in the bank after 9 years with a 5% interest rate compounded annually on a $2000 investment will be $3102.66.

Step-by-step explanation:

To find the amount in the bank after 9 years with compound interest, we can use the compound interest formula:

A = P (1 + r/n)nt

Where:

  • A is the amount of money accumulated after n years, including interest.
  • P is the principal amount (the initial amount of money).
  • r is the annual interest rate (decimal).
  • n is the number of times that interest is compounded per year.
  • t is the number of years the money is invested for.

Given:

  • P = $2,000
  • r = 5% or 0.05
  • n = 1 (since the interest is compounded annually)
  • t = 9 years

Now we calculate A:

A = 2000 (1 + 0.05/1)1*9

A = 2000 (1 + 0.05)9

A = 2000 (1.05)9

A = 2000 * 1.551328216

A = $3102.66

Therefore, the amount in the bank after 9 years, with interest compounded annually, will be $3102.66.
