Final answer:
Simple interest and compound interest calculations involve formulas that take into account the principle, rate, and time. For compound interest, the formula A = P(1 + r)^n is used. High risk in investments does not inherently mean low returns, as it represents potential for both high and low outcomes.
Step-by-step explanation:
Claudette's situation involves financial decisions such as investment and spending. To address some related concepts:
Calculating Interest from a Loan
For the total amount of simple interest from a $5,000 loan after three years at a simple interest rate of 6%, we use the formula I = Prt, where I is the interest, P is the principal amount, r is the rate of interest per year, and t is the time in years. Therefore, I = $5,000 * 0.06 * 3 = $900.
Determining Interest Rate
For the interest rate charged on a $10,000 loan upon receiving $500 in simple interest over five years, we rearrange the simple interest formula to r = I / (Pt). Hence, r = $500 / ($10,000 * 5) = 0.01 or 1% per annum.
Calculating Compound Interest
To find the value of a 5-year CD for $1,000 with a 2% annual compound interest rate, we use the formula A = P(1 + r)^n, where A is the amount, P is the principal, r is the annual interest rate, and n is the number of years. After calculating, A = $1,000(1 + 0.02)^5 ≈ $1,104.08.
Understanding Investment Returns
When comparing the average return over time between stocks, bonds, and a savings account, stocks tend to have a higher average return despite being more volatile. Bonds generally offer moderate returns with lower risk compared to stocks. A savings account usually provides the lowest return but is the safest investment.
Myth of High-risk and Low-return
The notion that a high-risk investment must yield a low return is not accurate. High risk can lead to both high or low returns, as risk is an inherent part of investing and reflects the potential variation in returns.
