Answer:
9.694 years
Step-by-step explanation:
Let the investment is $P.
So, we are asked to determine the time it will grow to triple with the compound interest rate of 12%.
Let the time is y years.
So, from the formula of compound interest we can write
⇒ 
⇒ 
Now, taking log both sides we get,
y log 1.12 = log 3 {Since, 
}
⇒ 0.04922y = 0.477712
⇒ y = 9.694 years (Answer)
Your answer would be -9 & -42.
Here's why ...
(-9)*(-42) A negative times a negative equals a positive (378).
Now, -9-42=-51 & you add these because you have two negatives.
Hope this makes sense & helps you ! (:
