Add 2.2 to each side so 0.3z = 5.2 - 0.5z -0.8z
add 0.5z to each side so 0.8z = 5.2 - 0.8z
add 0.8z to each side so 1.4z = 5.2
divide each side by 1.4 so z = 3.71428571
S represents the best distance from 1 and 0 to represent 33 1/3%
The answer would be B C E hope this helps :)
16x + 33y = 260, I think this is correct. Hope this helps!:)
