The formula for compound interest, including principal sum is:

, where

Let us use this rule to solve the question

∵ Ted invests $1,077 in a savings account with a fixed annual interest

   rat 9% compounded three times per year

∴ P = 1,077

∴ r = 9% = = 0.09

∴ n = 3 ⇒ three times per year

∵ The time is ten years

∴ t = 10

Substitute these values in the rule above to find A

∵

→ Use your calculator to find the answer

∴ A = 2,614.161681

→ Round it to the nearest cent (2d.p.)

∴ A = $2,614.16

∴ The account balance will be $2,614.16 after 10 years.
