    The answer to your question is: a folder cost $1.92

    Step-by-step explanation:

    Haley bought 8 pencils and 3 folders spent 10.39

    Nicole bought 5 pencils and 4 folders spent 10.51

    Folder = ?

    pencil = x

    folder = y

    Equations

    8x + 3 y = 10.39 (1)

    5x + 4 y = 10.51 (2)

    Solve these equations

    4 (8x + 3 y = 10.39) 32x + 12 y = 41.46

    -3 (5x + 4 y = 10.51) - 15x - 12y = -31.53

    17 x 0 = 9.93

    x = 9.93 / 17

    x = 0.58 pencil

    8 (0.58) + 3y = 10.39

    4.64 + 3y = 10.39

    3y = 10.39 - 4.64

    3y = 5.75

    y = 5.75 / 3

    y = 1.92 folder
