conversations.value: Can you guide me through solving this problem: Johnny makes his signature crab dish 40 times a day.  It uses 1.5 pounds of crab meat.  Crab meat sells for $8 per pound.  How much does he spend in a week if he is closed 3 days a week?
conversations.from: assistant
conversations.value: He uses 40*1.5=60 pounds of crab meat per day
  That cost 60*8=$480 per day
  He is open 7-3=4 days a week
  So he spends 480*4=$1920 a week
