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?
The pens and pencils were $1.00 each so 2*1 = $<T>multiply(2, 1)=2
The back pack cost $15 and the pens/pencils cost $2.00 so 15+2 = $<T>add(15, 2)=17
His total spent was $32 and he has already spend $17 so 32-17 = $<T>subtract(32, 17)=15
That means he has $15 left to spend on 5 notebooks so the cost would be 15/5 = $<T>divide(15, 5)=3.0 each
