Joe’s mother gave him $56 to go to the store. Joe bought 7 notebooks and 2 books. Each notebook costs $4 and each book costs $7. How much money does Joe have left?
7 notebooks cost 7 notebooks x $4/notebook = $<T>multiply(7, 4)=28
2 books cost 2 books x $7/book = $<T>multiply(2, 7)=14
In total Joe has spent $28 + $14 = $<T>add(28, 14)=42
He has $56 - $42 = $<T>subtract(56, 42)=14 left
