Answer: y = 4
Step-by-step explanation:
4 * 4 = 16
Well to find this answer, you want to divide $1.39 by 67.6. When you do this you get 0.0205. This is roughly 2 cents per ounce.
X = 3
and
formula -
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
(x1,y1) = (4,1)
(x2,y2) =( 5,3)
(y-1)/(x-4) = (3-1)/(5-4)
y-1/x-4 = 2/1
y-1 = 2x - 8
y = 2x - 7
the solution will be x= 3 and y = -1
