Question

A bat and a ball cost 1.10$ in total. The bat costs 1 dollar more than the ball. How much does the ball cost?

Answer 1

I believe it’s $0.10

Answer 2

$0.5

Explanation:

A + B = 1.10

A=1 +B

now A + B = 1.10

A - B = 1 (B cancels out)

2A = 2.10

A= 1.05

A + B = 1.10

substitute A value

1.05 + B = 1.10

B= 1.10-1.05

B=$ 0.5
