8 $\square$ (Round to the nearest cent as needed.)
Solution
Solution Steps
Step 1: Calculate Simple Interest (SI)
Using the formula \(SI = \frac{P \times R \times T}{100}\), where \(P = 5300\), \(R = 10\%\), and \(T = 4\) years,
we calculate the simple interest as \(SI = \frac{5300 \times 10 \times 4}{100} = 2120\).
Step 2: Calculate Compound Interest (CI)
Using the formula \(CI = P \times (1 + \frac{R}{100})^T - P\), where \(P = 5300\), \(R = 10\%\), and \(T = 4\) years,
we calculate the compound interest as \(CI = 5300 \times (1 + \frac{10}{100})^{4} - 5300 = 2459.73\).
Step 3: Find the Difference
The difference between the compound interest and the simple interest is calculated as \(Difference = CI - SI = 339.73\).
Final Answer:
The simple interest is 2120, the compound interest is 2459.73, and the difference is 339.73.
