    Ms.Sue... Steve or any other tutor that deals with math.. can you see if my answers are correct?

    1. p - .25p
    = 40 - .25(40)
    = 40 - 10 = 30 , so A

    2. correct

    3. 5^2 - 4/5 + 2
    = 25 - .8 + 2
    = 26.2 , correct

    4. (t^3 - r + 20) /4 , when r=4, t=2
    = (8 - 4 + 20)/4
    = 24/4 = 6 , so C
