A clothing store is having a clearance sale. All coats are 20% off, and then an additional $10 is taken off the sale price of each. A 7% sales tax is then added.
The following functions represent each part of the transaction.
Sales price: f(x) = 0.8x
Additional amount off: g(x) = x β 10
Final price: h(x) = 1.07x
Which is the composed function for the total price, x, of any item?
A) h(g(f(x))) = 1.07x β 10
B) h(g(f(x))) = 1.07(0.8x β 10)
C) h(g(f(x))) = 0.8x β 1.07
F) h(g(f(x))) = 1.07(0.8x β 10x)
