Answer:

The investment of $1000 that yields 12% interest per year would become $2000 in 6 years' time as shown by the calculation below

Explanation:

In determining the how long it would take for the investment to become $2000, the future value formula stated below is used.

FV=PV*(1+r)^N

FV is the $2000

PV, present value is $1000

r is the rate of return at 12%

2000=1000*(1+0.12)^N

2000/1000=1.12^N

2=1.12^N

by taking log of both sides the equation becomes

ln 2=N ln 1.12

N= ln 2/ln 1.12

N=6.116255374

approximately N is 6 years
