Q. Ayana has $400\$400 in a savings account that earns 10%10\% interest per year. The interest is not compounded. How much will she have in total in 11 year? Use the formula i=prti = prt, where ii is the interest earned, pp is the principal (starting amount), rr is the interest rate expressed as a decimal, and tt is the time in years. $\$_____
  1. Convert to decimal: Step 11: Convert the interest rate to a decimal. 10%10\% as a decimal is 0.100.10. Calculation: 10%/100=0.1010\% / 100 = 0.10
  2. Calculate interest earned: Step 22: Use the formula i=prti = prt to find the interest earned in one year.p=$400p = \$400, r=0.10r = 0.10, t=1t = 1. Calculation: i=400×0.10×1=$40i = 400 \times 0.10 \times 1 = \$40
  3. Find total amount: Step 33: Add the interest earned to the principal to find the total amount.\newlineTotal amount = Principal + Interest\newlineCalculation: $400+$40=$440\$400 + \$40 = \$440
