### Instruction:
Jonah bought 6 pineapples for $3 each. Each pineapple could be cut into 12 pineapple rings. He sold 4 pineapple rings for $5 each. How much profit did Jonah make?

### Response:
 ราคาสับปะรด: 6 x $3 = $<<6*3=18>>18
รายได้รวมจากการขายแหวนสับปะรด: 18 x $5 = $<<18*5=90>>90
กำไรรวม: $90 - $18 = $<<90-18=72>>72
