For the first scenario, you’re looking at a compound interest problem. You’re given all the information you need, so just input it into the compound interest equation.
A = P(1 + r/n)^nt
P is your principal, aka starting amount. That’s the 12000 people you start with.
R is your rate of interest, aka how much your principal is expanding by. That’s the 5% growth rate each year, or 0.05.
N is the number of times your principal grows each year. That’s only once here.
T is however long the change lasts. In this scenario, its from 2006 to 2020, so 14 years.
Input all this in and solve for A, which is your total amount.
A = 12,000(1 x 0.05/1)^(1 x 14) = 23,759.18
Since I doubt you can have 1/5 of a person, you round this down to 23,759, which is your answer.
I’d like to help with your second problem, but it’s cut off on the edge of the image, I can’t see all the numbers.

Answer:
Step-by-step explanation:
The possible outcomes include 1, 2, 3, etc., up through 25. This in itself is insufficient to specify who will go first. There must be some further criteria.
Suppose each player chooses and announces a number from this set by writing it down on a scrap of paper which is placed face-down on the table. The person who chooses the smaller number goes first. Or, the person who chooses the larger number goes first.
