Answer:
n=1
Step-by-step explanation:
-2(6 - 3n) + 27n = -3(n - 8)
-12+6n+27n=-3n+24
-12+33n=-3n+24
----------------------------
33n=-3n+36
+3 +3
-------------
36n=36
---- ----
n=1
Answer:
Function for given situation is : 
Value of computer after 4 years = $720.3.
Step-by-step explanation:
Given that the value of a $3000 computer decreases about 30% each year. Now we need to write a function for the computers value V(t). then we need to find about how much will the computer be worth in 4 years.
It clearly says that value decreases so that means function represents decay.
For decay we use formula:

where P=initial value = $3000,
r= rate of decrease =30% = 0.30
t= number of years
A=V(t) = future value
so the required function is 
or 
Now plug t=4 years to get the value of computer after 4 years.


Hence final answer is $720.3.
