How much do the notebooks cost? ** 7 notebooks cost 7 notebooks x $4/notebook = $<<7*4=28>>28
How much do the books cost? ** 2 books cost 2 books x $7/book = $<<2*7=14>>14
How much money did Joe spend? ** In total Joe has spent $28 + $14 = $<<28+14=42>>42
How much money does Joe have left? ** He has $56 - $42 = $<<56-42=14>>14 left
