### Instruction:
Fred had 236 dollars to spend on 6 books. After buying them, he had 14 dollars. On average, how much did each book cost?

### Response:
 Fred alikuwa na dola 236 za kutumia kununua vitabu 6. Alivinunua kwa dola 14 chini ya alivyokuwa nayo, hivyo 236 - 14 = dola 222.
Kila kitabu kiligharimu dola 222 / 6 = dola 37.
