Step-by-step explanation:
Comparision: Let say you buy chocolate that cost $1. And there was luckily a coupon, for 10% off.
That means after applying the coupon, you will only pay 90% of the original price. Which is
which equals 90 cents.
So let go back to this problem and apply similar thinking.
The price of the original root is g, so for the original price column, check the 3rd cell, g.
Use our comparision problem, by applying the coupon to the chocolate, you will save
which is 1/10 of the original price.
In this equation, we can represent this as 0.1g.
So for the second column, shade in 5th cell, 0.1g.
The price would be
So our equation for this equation will be
0.9g.
So for third column, shade in 1st cell, 0.9g.

Step-by-step explanation:
When the calculations are repetitive using the same formula, it is convenient to put the formula into a spreadsheet and let it do the calculations.
That is what was done for the spreadsheet below. The formula used is the one given in the problem statement.
__
For doubling time, the formula used is the one shown in the formula bar in the attachment. (For problem 11, the quarterly value was used instead of the monthly value.) It makes use of the growth factor for the period used for the rest of the problem.
The doubling time is in years.
__
The doubling time can also be found using a graphing calculator. In the second attachment, we have written a function that shows the multiplier for a given interest rate r and compounding n. The x-intercept in each case is the solution for t that makes the multiplier be 2. The steeper curve is associated with the higher interest rate.
