Dan spent $32 buying a new backpack, 1 pack of pens, 1 pack of pencils and 5 multi-subject notebooks for school. If the backpack costs $15 and both the pens and pencils cost $1.00 each, how much did each notebook cost? Let's think first. Chain of thought:
The pens and pencils were $1.00 each so 2 * 1 = $2.00. The back pack cost $15 and the pens / pencils cost $2.00 so 15 + 2 = $17.00. His total spent was $32 and he has already spend $17 so 32 - 17 = $15.00. That means he has $15 left to spend on 5 notebooks so the cost would be 15 / 5 = $3.00 each.
Therefore, the answer is 3.
