  1. 270 ÷ 9 = 30
    30 × 4 = $120 = Amanda
    270 ÷ 3 = $
    90 = Betty
    270 ÷ 6 = $45 = Cameron
    120 + 90 + 45 = 255
    270 - 255 = $
    15 = Dalia

    2. a + (a + 6) = 70
    2a + 6 = 70
    - 6
    2a = 64
    ÷ 2
    a = 32
    32 + 6 = 38
    Piece 1 = 32 inches
    Piece 2 = 38 inches

    I can't answer question 3 because I can't see the whole diagram, but I hope this helped!
