It's the same because you're trying to find net price (end price)
You're going to take in both scenarios 100%-15%= 85%
You're always going to be paying only 85% of the price.
Answer:

Step-by-step explanation:
Given


Required
Find f(x) and g(x)
Rewrite h(x)

If
then

This implies that; the expression in the brackets are equal;
In other words; function g(x) on the left hand side is equal to expression x + 2 on the right hand side
So;

To find f(x), substitute g(x) with x


Final solutions are

In the first statement, it is false. -2+14 would not add up to 16.
In the third statement, it is false. -8+-2 would not add up to 16.
In the fourth statement, it is false. -2-14 would not add up to 16.
So the second statement is true -2+18=16.
To find their mph:
192/3.5 = 54.857
So to answer how many miles they could drive at this rate in 6 hours
54.857 * 6 = 329.142 miles
