Amount Invested = \$50,000

Annual Interest Rate = 8.00%
Semiannual Interest Rate = 4.00%

Time Period = 3 years
Semiannual Period = 6

Accumulated Sum = Amount Invested * (1 + Semiannual Interest Rate)^Semiannual Period
Accumulated Sum = \$50,000 * 1.04^6
Accumulated Sum = \$50,000 * 1.265319
Accumulated Sum = \$63,265.95

Annual Deposit = \$10,000
Time Period = 3 years
Interest Rate = 6%

Accumulated Sum = \$10,000*1.06^3 + \$10,000*1.06^2 + \$10,000*1.06
Accumulated Sum = \$10,000 * 1.06 * (1.06^3 - 1) / 0.06
Accumulated Sum = \$10,000 * 3.374616
Accumulated Sum = \$33,746.16
