As time goes up, the number goes down
therefor we have an exponential function
we take 2 points (0, 25,000) and (1, 23,750) and use our trusty TI and find the equation
equatin is y=25000(0.95^x) or
f(x)=25000(0.95^x)

To solve this problem, we should set up an equation, letting x be the unknown number.
9 + x = 0
Next, we should subtract 9 from both sides to cancel out the +9 on the left side of the equation and get the variable alone.
x = -9.
Therefore, the number you are looking for is -9.
Answer:
Let's denote your original balance (at the beginning of the month) is x.
After depositing twice (24.61$ and 16.49$), you got 73.31$ as the amount of total money in your account.
=> x + 24.61 + 16.49 = 73.31
=> x = 73.31 - 24.61 - 15.49
=> x = 33.21$
