Step-by-step explanation:
If we are to find q(p(x)), we are to start at the innermost part of the problem which is p(x). Take the function p(x) and fill it into q(x) every place you see an x:
is the composition of p into q. Now all we have left to do is simplify.
Then we have to finally multiply in the 2 to get:
Hmmm what is now discounted? well, let's assume it sells normally for 499 and is discounted today at 25%, how much is that?
well, if we take 499 to be the 100, how much is 25%?
now, applying the sales tax to the discounted price.
if we take 374.25 to be the 100%, how much is 6.5%?
so, the total cost will then be 374.25 + t.
