Sales price: f(x) = 0.8x

Additional amount off: g(x) = x – 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 – 10
B) h(g(f(x))) = 1.07(0.8x – 10)
C) h(g(f(x))) = 0.8x – 1.07
F) h(g(f(x))) = 1.07(0.8x – 10x)

Which of the following expressions is equal to 2x^2+8
