c) You plan to make a series of deposits in an interest bearing account. You will
deposit R1000 today, R2000 in two years, and R8000 in five years. If you withdraw
R3000 in three years and R5000 in seven years, how much will you have after eight
years if the interest rate is 9%? (Assume annual compounding).
Answer
Answer:
Explanation: DEPOSIT NOW $1000 * FVIF 9%,8 PERIODS = $1000 * 1.9926 = $1992.6
IN 2 YEARS = $2000 * FVIF 9%,6 PERIODS = $2000 * 1.6771 = $3354.20
IN 5 YEARS = $8000 * FVIF 9%, 3 PERIODS = $8000*1.2950 = $10360
WITHDRAWAL: IN 3 YEARS = ($3000) * FVIF 9%, 5 PERIODS = ($3000) * 1.5386 = ($4615.80)
IN 7 YEARS = ($5000) * FVIF 9%, 1 PERIOD = ($5000) * 1.0900 = ($5450)
Total value = $1992.6 + $3354.20 + $10360 - $4615.80 - $5450
Total value = $5,641
So, the total future value after eight years is $5,641
