Final answer:

The future amounts for the investment of $500 with different compounding frequencies are $1,966.24 annually, $2,081.60 quarterly, and $2,208.00 monthly.

Step-by-step explanation:

To calculate the future amount of an investment with compound interest, we can use the formula:

A = P(1+r/n)nt

Where:

  • A is the future amount
  • P is the principal amount (initial investment)
  • r is the interest rate
  • n is the number of times interest is compounded per year
  • t is the number of years

Using this formula, we can calculate the future amounts for the given scenarios:

  1. Annually compounded: A = 500(1+0.12/1)1*20 = $1,966.24
  2. Quarterly compounded: A = 500(1+0.12/4)4*20 = $2,081.60
  3. Monthly compounded: A = 500(1+0.12/12)12*20 = $2,208.00
