Step 1: Understand the formula for Annual Percentage Yield (APY). APY is calculated using the formula: APY = (Interest Earned / Principal) × 100.
Step 2: Identify the given values from the problem. The principal (initial balance) is \$250, and the interest earned over one year is \$9.
Step 3: Substitute the given values into the formula. Replace 'Interest Earned' with \$9 and 'Principal' with \$250 in the formula: APY = (9 / 250) × 100.
Step 4: Perform the division first to calculate the fraction (9 ÷ 250). This will give you the decimal value representing the interest rate.
Step 5: Multiply the result of the division by 100 to convert the decimal into a percentage, which represents the APY.
