Answer:
A) rate of 12%
B) rate of 10%
Step-by-step explanation:
C = 10000
n = 5
PV = 36048
We solve for rate using a financial calculator or try an error or by looking at the PV tables of an annuitiues for the factor at n = 5 which equals PV/C
36048 / 10000 = 3.6048
this give us 12%
we do the same for b:
57,000 / 12,000 = 4.7500
we look for n= 7 for that facotr as; this is annuity-due (payment at the beginning)
which give us 10.000%
we could also use the rte function in excel:
=RATE(5;-12000;57000;;1)The first argument is the time period, then the installemtn and last the present value finally we add to excel that this is an annuity due.
