Identify Details:  Step 1: Identify the principal amount, interest rate, and time. Dale starts with $400 in his savings account. The interest rate is 10%, which we convert to a decimal for calculation, so r = 0.10. The time period is 1 year, t = 1. Calculation: p = 400, r = 0.10, t = 1Calculate Interest:  Step 2: Use the formula i = prt to find the interest earned in one year. Substitute the values into the formula: i = 400 * 0.10 * 1 Calculation: i = 400 * 0.10 * 1 = 40Total Amount Calculation:  Step 3: Calculate the total amount in the account after 1 year. Add the interest earned to the principal amount: Total = p + i = 400 + 40 Calculation: Total = 400 + 40 = 440
