a store is offering a discount of 30% on a suit. There is a sales tax of 6%.
A) using a composition of function, represent this situatio in which the discount is taken before the sales tax is applied. the answer is (1.06)(.7x) = .742x
B) using a composition of functions represent the situation in which the sales tax is applied before the discount is taken.the answer is (1.06x)(.7) = .742x
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.
i don't understand c can you help?

Plug a value for x (price of the suit) in each equation and then solve each equation.
This way you can see if one results in a lower price.
Explain why or why not, one equation results in a lower price.
