Answer:
P(t) = 27000 * (1/9)^(t/4)
Step-by-step explanation:
This problem can me modelled with an exponencial formula:
P = Po * (1+r)^t
Where P is the final value, Po is the inicial value, r is the rate and t is the amount of time.
In this problem, we have that the inicial population/value is 27000, the rate is -8/9 (negative because the population decays), and the time t is in months, so as the rate is for every 4 months, we use the value (t/4) in the exponencial.
So, our function will be:
P(t) = 27000 * (1-8/9)^(t/4)
P(t) = 27000 * (1/9)^(t/4)

Solution:






that's why the answer is correct.
It is a simple multiplication problem. If you work for 39 hours, and you get paid $8.17 for every hour you work, just multiply 8.17 by 39 to get the gross pay.
8.17 x 39 = 318.63
The gross pay is $318.6.
Hope this helps =)
I think ordered pair D would be the correct one
