Final answer:

The value of Evan's investment after three years with a compound interest rate of 4% per annum is $2249.73, obtained by using the compound interest formula with the principal amount of $2000.

Step-by-step explanation:

To calculate the value of Evan's investment after three years with a 4% per annum compound interest rate, 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 time the money is invested for, in years.

For Evan's investment:

  • P = $2000
  • r = 4% or 0.04
  • n = 1 (compounded annually)
  • t = 3 years

Thus, we substitute the values into the formula:


A = 2000(1 + 0.04/1)1\*3


A = 2000(1 + 0.04)3

A = 2000(1.04)3

The calculation will yield the final amount after three years:

A = 2000\*1.124864 = $2249.73

The value of Evan's investment after three years, compounded annually at a 4% rate, will be $2249.73.
