## 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 **$0.05**.

The bat then costs $1.05, and $1.05 + $0.05 = $1.10 — with the bat exactly $1.00 more than the ball. (The instinctive answer of $0.10 is wrong, since that would make the bat $1.10 and the total $1.20.)
