Answer: 7%
Step-by-step explanation:
Given data:
P = $5,000
r = ?
t = 40years
i = $1,000,000
Solution:
NFW = 0 = -$5000 ( F/A , i , 40 ) + $1,000,000
( F/A , i , 40 ) = $1,000,000 / $5,000
= 200
From compound interest table
( F/A , 7% , 40 ) = 199.636
Therefore the return for the investment would be 7%
