Hey can you me posted picture of question

Well, there are 50 patrons in total. We know 16 like lattes, 12 like espressos and 8 of them like both. 16 + 12 + 8 = 36 patrons who like coffee. So to find the patrons who do not like coffee, we need to find the rest of the patrons, we do that by taking 36 away from 5050 - 36 = 14. There are 14 patrons that don't like coffee. Answer = 14 = c

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
