Answer: The answer is given below
Explanation:
Based on the explanations and the figures provided on the question, the solution goes thus:
a. Assuming that the inflation rate is also be the rate of growth in savings amount i.e the income of an individual will grow minimum by inflation amount.
r = 8% = 8/100 = 0.08
g = 2% = 2/100 =0.02
Future value = 15000[(.08)^30 - (1.02)^30)]/0.06
Fv= 2062250
b) similarly for b as expense ratio of mutual fund is said to be higher, we will get:
r=7.5% = 7.5/100 = 0.075
g= 2% = 2/100 = 0.02
fv= 15000[(1.075)^30 - (1.02)^30)]/0.055 Future value = 1892454
we can therefore deduce that due to the increase in expense ratio assets in the 2nd scenario, the value are less by:
= 2062250 - 1892454
= 169,796.
