(IF the problem was to get the price with the sales tax added, rather than just the sales tax itself, then g(x)= x+ .06x= 1.06 x.)
Here, we clearly want the price with the sales tax added. This is now f(g(x)) with the g(x)= 1.06 x.b. Using a composition of functions, represent the situation in which the sales tax is applied before the discount is taken.
[/quote]c. Compare the composite functions from parts a and b. Does one of them result in a lower final cost? Explain why or why not.
Any help or advice would be greatly appreciated!!
