Precious borrows money from Steven at a simple discount rate of 9,75% per year. She must
pay him R35 000 in 27 months’ time. The amount of money that she receives from Steven
now is
[1] R42 678,13.
[2] R28 703,23.
[3] R28 389,51.
[4] R44 835,87.
[5] R27 321,88.
This is a simple discount calculation as the term discount rate is found in the
question. The formula for simple discount is P = S(1 − dt).
Given are the future value of the loan (S) which is R35 000, the time period which
equals 27 months and the discount rate (d) of 9,75%. The time period that we use
must always be in years.
As the given time is in months we change it to a fraction of a year by dividing the
months by the number of months in a year which is 12. Thus t = Now we need to
determine the present value of the loan. Thus:
P = S(1 − dt)
= 35 000 (1 – 0.0975 × )
= R27 321.875….
