Answer:
1. (-3,-11),(-2,-8),(-1,-5),(0,-2)(1,1)(2,4) (3,7)
2 (-3,5),(-2,0),(-1,-3), (0,-4),(1,-3),(2,0),(3,5)
Let's set up two equations:
x+y=20 We know she brought total of 20, some of each so x=small y=big
20x+ 30y=450
x+y= 20
-y -y
------------
x= 20 -y
substitute into the other equation:
20 (20-y) + 30y = 450
400 - 20y + 30y = 450
400+ 10 y = 450
10 y = 50
y= 5
So she brought 5 big cases. Then substitute the value of y into one of the equations.
5+ x = 20
x= 15
So we bought 15 small cases and 5 big cases.

Answer: A:3 rolls B: $38.67
Step-by-step explanation:
1. Convert all units to the same value (feet to inches, as the opposite gives fractions)
2. Use new equation and multiply the said new variable (84*3 & 96*3)
3. The new total should amount to the total area (540)
4. Divide found area by 12 to convert back into feet (45)
5. Divide the feet by feet per roll (3)
6. Multiply for Cost
I am pretty sure you would do 396x.25 on a calculator and then do that answer and x's it by 3 and that equals 297
