<human>:  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?
<bot>: How much does Melissa make per day? ** First find Melissa's net daily pay by subtracting the parking expense from her $15 gross pay: $15/day - $3/day = $<<15-3=12>>12/day
How much does Melissa make per hour? ** 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 = $<<12/6=2>>2/hour
