## Prompt

A bat and a ball cost $1.10 together. The bat costs $1.00 more than the ball. How much does the ball cost?

## Response

The ball costs 5 cents. Many people intuitively answer 10 cents, but that leads to an inconsistent total.  

## Correct Breakdown
- Let the ball cost \( x \).  
- The bat then costs \( x + 1 \).  
- Their sum equals 1.10, so \( 2x + 1 = 1.10 \).  
- Solving gives \( x = 0.05 \).  

The ball is therefore $0.05 and the bat is $1.05.
