Q3. In question 1 , determine the length of time required for the investment to double in value, to quadruple.

Q4. In question 2, determine the length of time required for investment to double in value, to triple.

Please do not put multiple problems in the same post.

Furthermore, please show us your work so we can see where you are stuck. If you were not able to start, what ideas did you consider. Hard to know how to help if we have no clue where you are having difficulty.

In problem 1 is the interest rate 8%? Compounded how frequently?
