Final answer:
The total dollar amount of return on the investment is $3, and the percentage return on the investment is 3%.
Step-by-step explanation:
The student's question pertains to the calculation of total dollar amount and percentage return on an investment over a period of one year. To find the total dollar amount of return, subtract the initial investment from the final amount received from selling the stocks. In this case, you would subtract $100 (initial investment) from $103 (amount received after selling the stocks) to get a dollar return of $3. To calculate the percentage return, divide the dollar return by the initial investment and then multiply the result by 100. So, the percentage return is calculated as ($3 / $100) × 100, which equals 3%.
