Answer:
invested amount = $5,089.9
Explanation:
given data
invested = $5,000
interest rate = 8%
time = 25 year
interest rate = 10%
time = 20 year
solution
we get here interest amount that is
amount = invested × [tex](1+r)^{t}[/tex] .............1
amount = $5,000 × [tex](1+0.08)^{25}[/tex]
amount = $34,242.38
and
now we consider here x amount is invested so here we get invested amount in 20 year with 10 % rate
amount = invested × [tex](1+r)^{t}[/tex] .............2
$34,242.38 = invested × [tex](1+0.10)^{20}[/tex]
invested amount = $5,089.9
