Q. Amy has $90\$90 in a savings account. The interest rate is 10%10\% per year and is not compounded. How much will she have in total in 22 years? \newlineUse the formula i=prti = prt, where ii is the interest earned, pp is the principal (starting amount), rr is the interest rate expressed as a decimal, and tt is the time in years.\newline$\$_____\_\_\_\_\_
  1. Initial Amount and Rates: Amy's starting amount (principal) is \$\(90\), and the interest rate is \(10\%\) per year, which is \(0.10\) as a decimal. The time is \(2\) years.
  2. Calculate Interest: Use the formula \(i = prt\) to calculate the interest. So, \(i = (\$90) \times 0.10 \times 2\).
  3. Interest Calculation: Calculate the interest: \(i = (\$90) \times 0.10 \times 2 = (\$18)\).
  4. Total Amount Calculation: Add the interest to the principal to find the total amount after \(2\) years. Total = \(\$90\) + \(\$18\).
  5. Final Total Calculation: Calculate the total: Total = \(\$90\) + \(\$18\) = \(\$108\).
