Answer:
The investment in 42 years will become $115199.88
Step-by-step explanation:
Let the investment model is @@MATH_TOKEN_0@@
A = final amount
P = initial amount
r = rate
t = time
Now, given that
P = $1800
A = 2P = 2×1800 = $3600
t = 7 years
@@MATH_TOKEN_1@@
Now, we have to find A for t = 42 years
@@MATH_TOKEN_2@@
Hence, the investment in 42 years will become $115199.88
