From reading the problem we see that y = 0 and x = 16.
To find the correct equation, simple plug in the values for x and y for each equation and see which equation is true.
The correct answer is 5x + 4y = 80
5(16) + 4(0) =80
80 + 0 = 80
80 = 80
5.5x + 3 = y
7x =y
5.5x + 3 = 7x (-5.5x both sides)
3 = 1.5x (÷1.5 both sides)
X = 2

208/16 = 13 yards per part
13-4 = 9 yards of unpainted strip per strip
9*16 = 144 of unpainted strips

x= 80,000/.4
x = 200,000</span>
