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 = $<<7*4=28>>28
2 books cost 2 books x $7/book = $<<2*7=14>>14
In total Joe has spent $28 + $14 = $<<28+14=42>>42
He has $56 - $42 = $<<56-42=14>>14 left
