Answer: A. $82.50
Explanation: First, calculate how much wall will be covered. Two sides of the room are 17 ft, and two are 16 ft. That’s a total of 66 ft of wall. (17 + 17 + 16 + 16 = 66.) Now, multiply by the cost of wallpaper. 66 * 1.25 = 82.5.

Answer:
(0,-4)
Step-by-step explanation:
x-y = 4
2x+y = -4
Add these together to eliminate y
x-y = 4
2x+y = -4
-------------------
3x = 0
Divide by 3
3x/3 = 0/3
x = 0
Now we need to find t
2x+y = -4
0+y = -4
y= -4
