    x=bat
    y=ball

    Given:
    1. x + y = 1.1
    2. x - y = 1
    Rearranging 2:
    3. x = y + 1
    Substituting 3 into 1:
    y + 1 + y = 1.1
    Solving:
    2y = 0.1
    y = 0.05

    bat + ball = 110
    bat = ball + 100

    So, ball + ball + 100 = 110
    2 balls = 10
    ball = 5

    Ans. The ball costs 5 pence.


    Edit: Where did you buy them?
