conversations.value: Can you break down the solution for me for this math problem: Carmen is selling girl scout cookies. She sells three boxes of samoas to the green house for $4 each; two boxes of thin mints for $3.50 each and one box of fudge delights for $5 to the yellow house; and nine boxes of sugar cookies for $2 each to the brown house. How much money did Carmen make?

conversations.value: Carmen earned 3 * $4 = $12 at the green house.
  She earned 2 * $3.50 = $7 for the mints.
  She earned $7 + $5 = $12 at the yellow house.
  She earned 9 * $2 = $18 at the brown house.
  So, Carmen earned a total of $12 + $12 + 18 = $42.
