Answer:
47 bags
Step-by-step explanation:
A company makes 120 bags.
40 of the bags have buttons but no zips.
43 of the bags have zips but no buttons.
33 of the bags have neither zips nor buttons
so
120 total bags - 40 (no zips) - 33 (neither zips nor buttons) = 47
therefore
the number of bags that have zips on them is 47 bags.
