Du Chin bakes 200 meat pies in a day. He sells them for $20 each and uses 3/5 of the sales to buy ingredients to make meat pies for sale on the next day. How much money does Du Chin remain with after setting aside the money for buying ingredients?
From the 200 meat pies, Du Chin makes 200*$20 = $<<200*20=4000>>4000 after the sales.
The amount of money he uses to buy ingredients to make pies for sale on the next day is 3/5*$4000 = $<<3/5*4000=2400>>2400
After setting aside money for buying ingredients, Du Chin remains with $4000-$2400 = $<<4000-2400=1600>>1600
