### Instruction:
John reels in 3 crab baskets a week.  Each basket holds 4 crabs.  He collects crabs twice a week.  Each crab sells for $3.  How much money does he make?

### Response:
 Kila mara anapovua kamba hupata 3*4=<<3*4=12>>12 kamba.
Hivyo hupata 12*2=<<12*2=24>>24 kamba kwa wiki.
Hivyo anapata 24*3=$<<24*3=72>>72 kwa wiki.
