Answer:
Option A.
Step-by-step explanation:
The given functions are
we need to find the function (f-g)(x).
Using the composition of functions the subtraction of two functions is defined as
Substitute the given values of functions f(x) and g(x).
On combining line terms we get
Therefore, the correct option is A.

Answer:
$37.
Step-by-step explanation:
Firstly, let's set the price of each pair of shoe to be x.
Since each pair of shoes costs the same, and there are three pairs, we can set the original price to be 3x.
Now, to apply the shipping charge, all we have to do is add 7.50 to 3x, getting 3x + 7.5.
Next, to apply a 6% tax, we can multiple the whole expression by (100% + 6%), getting (3x + 7.5) 106%.
Since the whole bill foots to a total of $126.81, we can set the final equation to be:
