Step-by-step explanation:
This question is solved by rule of three, due to proportions.
One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?
1 foot - 3 dollars
3/4 foot - x dollars
![x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25](https://tex.z-dn.net/?f=x%20%3D%203%20%5Ctimes%20%5Cfrac%7B3%7D%7B4%7D%20%3D%20%5Cfrac%7B9%7D%7B4%7D%20%3D%202.25)
So
3/4 of a foot will cost $2.25.
Answer:
(-0.4, 4)
x+y=3.6 /*(-1)
2x+y=3.2

x= -0.4
-0.4+y=3.6
+0.4 0.4
y= 4
