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.
How many bags have zips on them?

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.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
