To calculate the interest earned and the final amount in an account using simple interest, you can use the following formulas:

  1. Simple Interest (I): \[ I = P \times r \times t \] where:

    • \( P \) = principal amount (initial investment)
    • \( r \) = annual interest rate (as a decimal)
    • \( t \) = time (in years)
  2. Final Amount (A): \[ A = P + I \]

Given:

  • \( P = 10,000 \)
  • \( r = 4.75% = \frac{4.75}{100} = 0.0475 \)
  • \( t = 13 \)

Now, calculate the interest earned:

\[ I = 10,000 \times 0.0475 \times 13 \] \[ I = 10,000 \times 0.0475 \times 13 = 10,000 \times 0.6175 = 6175 \]

So, the interest earned is $6,175.00.

Next, calculate the final amount:

\[ A = P + I = 10,000 + 6175 = 16175 \]

So, the final amount in the account after 13 years is $16,175.00.

Putting it all together:

  • The accrued interest is $6,175.00.
  • The final amount in the account at the end of the 13 years is $16,175.00.
