There are 42 people in pilates class. Today, 36 of them brought yoga mats, 26 of them brought eco-friendly water bottles, and 20 of them remembered to bring both yoga mats and water bottles. How many people had to suffer through class having neither a yoga mat nor a water bottle?

 

im not really sure how to start... heh...

There are 36 - 20 = 16 people who brought yoga mats but no water bottles. There are 26 - 20 = 6 people who brought water bottles but no yoga mats. Therefore, 16 + 6 = 22 people had to suffer through class having neither a yoga mat nor a water bottle. So the answer is 22
