Transcript text: Find the total amount in the compound interest account. $\$ 1750$ is compounded daily at a rate of $10 \%$ for 5 years. Let 1 year $=365$ days. \$ $\square$ (Do not round until the final answer. Then round to the nearest hundredth as $n^{-1}$ d.)
Solution
Solution Steps
To find the total amount in a compound interest account, we use the compound interest formula:
\[ A = P \left(1 + \frac{r}{n}\right)^{nt} \]
where:
\( A \) is the amount of money accumulated after n years, including interest.
\( P \) is the principal amount (the initial amount of money).
\( r \) is the annual interest rate (decimal).
\( n \) is the number of times that interest is compounded per year.
\( t \) is the time the money is invested for in years.
Given:
\( P = 1750 \)
\( r = 0.10 \)
\( n = 365 \) (compounded daily)
\( t = 5 \)
We will plug these values into the formula to find \( A \).
Step 1: Identify the Given Values
We are given the following values:
Principal amount, \( P = 1750 \)
Annual interest rate, \( r = 0.10 \)
Number of times interest is compounded per year, \( n = 365 \)
Time in years, \( t = 5 \)
Step 2: Apply the Compound Interest Formula
The compound interest formula is:
\[ A = P \left(1 + \frac{r}{n}\right)^{nt} \]
Step 3: Substitute the Given Values into the Formula
Substituting the given values into the formula, we get:
\[ A = 1750 \left(1 + \frac{0.10}{365}\right)^{365 \times 5} \]
Step 4: Calculate the Result
Performing the calculation:
\[ A = 1750 \left(1 + \frac{0.10}{365}\right)^{1825} \]
\[ A \approx 2885.06 \]
Final Answer
The total amount in the compound interest account after 5 years is:
\[ \boxed{2885.06} \]
