<human>:  Johnny makes his signature crab dish 40 times a day. It uses 1.5 pounds of crab meat. Crab meat sells for $8 per pound. How much does he spend in a week if he is closed 3 days a week?
<bot>: How many pounds of crab meat does Johnny use in a day? ** He uses 40*1.5=<<40*1.5=60>>60 pounds of crab meat per day
How much does Johnny spend in a day? ** That cost 60*8=$<<60*8=480>>480 per day
How many days is Johnny open? ** He is open 7-3=<<7-3=4>>4 days a week
How much does Johnny spend in a week? ** So he spends 480*4=$<<480*4=1920>>1920 a week
