conversations.value: Solve the following math problem: Melissa is summoned to jury duty. She spends 6 hours a day for 3 days listening to a court case. If Melissa is paid $15 per day but also has to pay $3 for parking each day, how much jury pay does she make per hour after expenses?

conversations.value: First find Melissa's net daily pay by subtracting the parking expense from her $15 gross pay: $15/day - $3/day = $12/day
  Then divide this number by the number of hours Melissa spends in court each day to find her hourly pay: $12/day / 6 hours/day = $2/hour
