To calculate the interest earned using simple interest, you can use the formula:
\[ I = P \times r \times t \]
Where:
- \( I \) is the interest earned
- \( P \) is the principal amount (the initial investment)
- \( r \) is the annual interest rate (in decimal)
- \( t \) is the time in years
In this scenario:
- \( P = 10,000 \)
- \( r = 4.75% = 0.0475 \)
- \( t = 13 \)
Now plug these values into the formula:
\[ I = 10,000 \times 0.0475 \times 13 \] \[ I = 10,000 \times 0.0475 \times 13 = 6,175 \]
The interest earned is $6,175.
To find the final amount in the account after 13 years, you can use the following formula:
\[ A = P + I \]
Where:
- \( A \) is the total amount in the account
- \( P \) is the principal amount
- \( I \) is the interest earned
Substituting the values:
\[ A = 10,000 + 6,175 = 16,175 \]
The final amount in the account after 13 years is $16,175.
Thus the answers to fill in are:
The accrued interest is $6,175 and the final amount in the account at the end of the 13 years is $16,175!
