Answer:
$90 trillion
Explanation:
The equation that describes compound interest is:
[tex]FV = PV*(1+r)^t[/tex]
Where "FV" is the future value, "PV" is the present value ($35), "r" is the interest rate (0.075) and "t" is the time invested, in years (395).
Applying the given data, their investment would be worth:
[tex]FV = 35*(1+0.075)^{395}\\FV = \$89,209,565,422,347.12[/tex]
Their investment would be worth roughly $90 trillion today.
