Final answer:
To calculate the interest earned, use the formula: Interest = Principal × Rate × Time.
Step-by-step explanation:
The question is asking about a sum of money, represented by R^(8000), that is lent at the beginning of the year at a certain simple interest rate. In simple interest, the interest earned is calculated by multiplying the principal (the initial amount) by the rate of interest and the time period.
To calculate the interest earned, we can use the formula: Interest = Principal × Rate × Time. The answer to the question will depend on the specific values of the principal, rate, and time.
For example, let's say the principal is $10,000, the rate is 1%, and the time is 5 years. Using the formula, we can calculate the interest as follows: Interest = $10,000 × 0.01 × 5 = $500.
