There are 6 yellow marbles and 14 red marbles. 6 + 14 = 20
The probability of selecting a red/yellow marble is a 20 out of 27 chance.
(g₀f)(x)=g(f(x))
=g(2x-2)
=5(2x-2)^2-3
=5(4x^2-8x+4)-3
=20x^2-40x+17
Muliply 65 and 0.12 and get 7.8
Subtract 65-7.8 to get marked down price
57.2 is the price after markdown
All you do is divide -12/20 by 4/4 which is -3/5
