The answer is F(x) = 900x + 600

Let x stands for the number of months

The apartment is rented for $900 a month, so every month it will be paid 900x (for example, for one month (x = 1), you will pay 900 · 1 = $900, for three months (x = 5), you will pay 900 · 5 = $4500, etc.)

A security deposit is paid only once and is not dependent on the number of months. So, its value is only 600.

These two values must be summed up because both must be paid, nothing is to subtract. Therefore, the function f(x) for apartments that rent for $900 a month and a security deposit of $600 is:
f(x) = 900x + 600

Answer:

45158

Step-by-step explanation:

Since the colony grows at a rate of 12%, after 2 years there will be $36000\cdot 1.12^2 = 45158.4$ bacteria. Since you probably can't have part of a bacteria, you round to 45158.
