    Answer:

    Pen: $0.03

    Pencil: $0.14

    Step-by-step explanation:

    let x be the cost of 1 pencil

    this means that the cost of a pen would be x + 0.11

    Since she bought 250 pens and 250 pencils, that would be:

    250x + 250(x + 0.11) = 42.5

    solve:

    250x + 250(x + 0.11) = 42.5\\250x + 250x +27.5=42.5\\500x = 15\\x = 0.03

    This means that the cost of a pencil is $0.03 and the cost of a pen is 11 cents greater, so $0.14.
