  2. A)
    x + 0.28x = 54.32

    B)
    54.32 - 0.8x - 0.20x = x

    C)
    x + 0.08x + 0.20x = 54.32

    D)
    .20(x + 0.08x) + (x + 0.08x) = 54.32

  9. actually it is not D
    Let the original amount be x
    after tax ----- 1.08x
    then the tip ----- (1.2)(1.08x) = 54.32
    x = 41.91

    check:
    tax = .08(41.91) = 3.35
    total after tax = 45.27
    tip = .2(45.27) = 9.05
    total bill = 54.32

    none of your given equations are satisfied by my correct answer.

  11. cost = $X before tax and tip.
    x + 0.08x + 0.2(x+0.08x) = 54.32.
    1.08x + 0.216x = 54.32,
    X = $41.91.
    The answer is D.
