There are 42 people in pilates class. Today, 36 of them brought yoga mats, 26 of them brought eco-friendly water bottles, and 28 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?
+37146 Your numbers don't 'work' .... if 26 brought water bottles....how can 28 have brought water bottles and yoga mats ?
