PLEASE$$EXPLAIN DETAILSLet's assume that the real rate of return is a constant $20\%.$ If

inflation is $50\%,$ then the nominal rate of return is $80\%($because

$(1+0\mathrm{.}50)*(1+0\mathrm{.}20)=1\mathrm{.}80).$ Therefore, you get $$180$ over a one year

period for a $$100$ investment. Assuming income taxes to the tune of

$40\%,$ compute the real value of your investment $($after taxes on

nominal income have been paid$)$ at the end of the year. Now contrast

the same scenario but without any inflation, what would the value

of your investment be at the end of the year. What lesson can we

learn comparing these two scenarios? $[15$ marks$]$
