T= total cost
W= weeks
It can't be W= because the question is asking for total cost in dollars, so two options are cancelled out.

Step-by-step explanation:
7 raised to -1 - 8 raised to -1 whole raised to -1 is 56
3 raised to -1 - 4 raised to -1 whole raised to -1 is 12
Answer:

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

So then we need to replace the value of x =3 and we got:

Step-by-step explanation:
For this case we have the following function:

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

So then we need to replace the value of x =3 and we got:
