## 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** (5 cents).

The bat costs $1.05, so together:

\[
\$1.05 + \$0.05 = \$1.10
\]

Would you like a quick explanation of why the intuitive 10-cent answer is incorrect?
