Johnny makes his signature crab dish 40 times a day.  It uses 1.5 pounds of crab meat.  Crab meat sells for $8 per pound.  How much does he spend in a week if he is closed 3 days a week?
He uses 40*1.5=<T>multiply(40, 1.5)=60.0 pounds of crab meat per day
That cost 60*8=$<T>multiply(60, 8)=480 per day
He is open 7-3=<T>subtract(7, 3)=4 days a week
So he spends 480*4=$<T>multiply(480, 4)=1920 a week
