    1. 401 + 18*x*z, for z = 10

    we plug in z = 10,

    401 + 18*x*10
    401 + 180x

    2. 55 - K/6 for k = 30

    we plug in k = 30,

    55 - 30/6
    55 - 5
    50


    3. 32 + 55 x b/11 for b = 2

    let us see you try to do 3 by substituting b=2, I'll correct you if you make a mistake.
