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