The answer is 387. Let's see why.
Step-by-step explanation:
The computer costs $1548. And all the 12 payments are <u>equal.</u>
To find one payment we need to divide the total cost to the number of payments.

Each one of the payments is $129.
To find three payment we simply follow:
129 . 3 = <u>387</u>
Another solution can be;
Since we are looking for 3 of the payments we can divide it to the total payment
which equals to 
And we can find the answer by multiplying it with the cost which gives;

Answer:

Answer:
3
Step-by-step explanation:
f(3) = 2*3 -3
= 6-3=3
f(f(3)) = f(3)
so again,
f(3) = 2*3 -3
= 6-3= 3
Take your original equation 
and multiply both sides by
to remove the fractions. You are left with

So, 
Update: There is no numerical answer that can be found without being given a value for either x or y
