The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. marco is studying the change in the
amount of money in two accounts, a and b, over time.
the amount f(x), in dollars, in account a after x years is represented by the function below:
f(x) = 10,125(1.83)*
part a: is the amount of money in account a increasing or decreasing and by what percentage per year? justify your answer. (5 points)
part b: the table below shows the amount in dollars, of money in account b after r years:

r (number of years)
g(t) (amount in dollars) 9,638
10 36,648.50 71,464.58

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
