Answer:
186.3
Step-by-step explanation:
Because 186.3 / 20.7 is 9
g(x) = 2x-6
f(x) = -4x +7
(g•f)(x) = g(f(x))
= 2(f(x)) - 6
= 2 ( -4x+7) -6
= -8x + 14 -6
= -8x +8
now
(g•f)(1) = -8(1) + 8= -8+8
= 0
so option a is answer
C
Because .75 times 9 would give you the price of the books and then you would have to add C, the amount left to get to 20.
