To calculate the amount Wallace must invest today, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = the future value of the investment (R 5 000)
P = the principal amount (the amount Wallace must invest today)
r = the annual interest rate
n = the number of compounding periods per year
t = the number of years the money is invested for
For the first three years:
A = P(1 + 0.08/1)^(1*3)
A = P(1.08)^3
A = 1.25971P
For the remaining two years:
A = P(1 + 0.09/2)^(2*2)
A = P(1.045)^4
A = 1.21873P
Since the total future value is R 5 000, we can set up the equation:
1.25971P + 1.21873P = 5000
2.47844P = 5000
P = 5000 / 2.47844
P ≈ R 2018.58
Therefore, Wallace must invest approximately R 2018.58 today to receive R 5 000 in 5 years time.
