###Human: Tom receives a $12 allowance per month. In the first week, he spends a third of it; in the second week, he spends a quarter of what he has left. How much money does he have left to finish the month?, ### Assistant: The first week he spends: $12 * 1/3 = $4.
So he has $12 - $4 = $8 left.
In the second week, he spends $8 x 1/4 = $2.
So Tom has $8 - $2 = $6 left to finish the month. 
 So the answer is :  6
