Q. Leo has 2020 $\$ in an account that earns 5%5\% interest compounded annually. To the nearest cent, how much will he have in 11 year? Use the formula B=p(1+r)tB = p(1 + r)^t, where BB is the balance (final amount), pp is the principal (starting amount), rr is the interest rate expressed as a decimal, and tt is the time in years. $\$____
  1. Identify Formula and Values: Step 11: Identify the formula and values to use.\newlineWe use the formula B=p(1+r)tB = p(1 + r)^t. Here, p=$20p = \$20, r=5%r = 5\% (or 0.050.05 as a decimal), and t=1t = 1 year.
  2. Substitute Values: Step 22: Substitute the values into the formula.\newlineCalculate B=20(1+0.05)1B = 20(1 + 0.05)^1.
  3. Perform Calculation: Step 33: Perform the calculation.\newlineFirst, calculate 1+0.05=1.051 + 0.05 = 1.05.\newlineThen, 20×1.05=2120 \times 1.05 = 21.
