## 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** (\$0.05), and the bat costs **\$1.05**.

If the ball cost 10 cents, the bat would cost \$1.10 (one dollar more), making the total \$1.20—not \$1.10. The correct solution:

\[ x + (x + 1.00) = 1.10 \]
\[ 2x = 0.10 \]
\[ x = 0.05 \]
