Answer:
66
Step-by-step explanation:
42+8x
= 42+8(3)
= 42+24
= 66
You take 50/4 which equals 12.5
so now you say “well one sub is 2.95”
take that and multiply it by 12
12 x 2.95 = 35.4
then you take 2.95 and divide it by 2 that is 1.48
so now you take 35.4 + 1.48
the cost should be 36.88
Answer: 465

The answer is:

<h2>
Why?</h2>
To composite functions, we need to evaluate functions in another function(s), for example:
Given f(x) and g(x), if we want to calculate f(x) composite g(x), we need to evaluate g(x) into f(x).
So, we are given the functions:

And we are asked to calculate g(x) composite f(x), and then evaluate "x" to 0, so, calculating we have:

Now that we have the composite function, we need to evaluate "x" equal to 0, so:

Hence, we have that:

Have a nice day!
