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?
