Premise 1:
bat + ball = 1.1
Premise 2:
bat = ball + 1
Therefore, from premise 2 we can alter premise 1:
ball + 1 + ball = 1.1
2ball + 1 = 1.1
2ball = 0.1
Result 1:
ball = 0.5
Splicing result 1 in to premise 1 :
bat + 0.5 = 1.1
Result 2:
bat = 1.05
The ball costs 5 cents, the bat one dollar and five cents.
