Answer:
The rate of return is 8.96%
Step-by-step explanation:
The rate of return required here can be computed using excel rate formula ,which is stated thus:
=rate(nper,-pmt,pv,fv)
nper is the duration of investment which is 9 years
pmt is the yearly invested sum of $1,200
pv is the present worth of total invested sum which is unknown and taken as zero
fv is the future accumulated investment amount of $15,600
=rate(9,-1200,0,15600)=8.96%
