A pad of loose-leaf paper is $0.40 less than a notebook. Together they cost $1.80. How much does the loose-leaf paper cost?? The notebook?

  • math - ,

    Let x = the pad of paper.


    x + x - 0.4 = 1.80

    2x = 1.40

    x = 0.70

  • math - ,

    P + N = 1.80
    N = P + .40

    P +(P+ .40) = 1.80

    2 P = 1.40

    P = 0.70

    N = P+ .40 = 1.10

    I beleive the answer is the notebook cost $1.30. and the loose leaf paper cost $0.50.
