conversations.value: Can you give me some step-by-step instructions for this math problem: Rose is an aspiring artist. She wants a paintbrush that costs $2.40, a set of paints that costs $9.20, and an easel that costs $6.50 so she can do some paintings. Rose already has $7.10. How much more money does Rose need?

conversations.value: The total cost of the paintbrush, the paints, and the easel was $2.40 + $9.20 + $6.50 = $18.10.
  Rose needs $18.10 - $7.10 = $11 more.
