Dashiel invests $1,000 at a simple interest rate of 3% per year. What is the sequence of amounts in his investment account at the start of the investment and at the end of each of the next three years?

Simple interest is calculated on the original $1,000 each year. Three percent of $1,000 is $30, so the balance increases by $30 annually: $1,000 at the start, then $1,030, $1,060, and $1,090. This matches choice A.
