Marita can make 36 banners since 3 feet are in a yard and she orders 12 yards then she will have 36 feet of ribbon and she needs 1 foot for every banner, so she can make 36 banners.
The easiest way to solve this system of equations is by elimination. Both equations have a 3x term, so we can basically subtract the equations to cancel the 3x. Then we will be left with a single variable to solve for.
(3x + y = -4)
-(3x -4y = 6)
Distribute the negative:
(3x + y = -4)
(-3x + 4y = -6)
Now add the equations together term by term:
0x + 5y = -10
5y = -10
y = -2
Plug y = -2 into either equation to find x.
3x + (-2) = -4
3x = -2
x = -2/3
So the answer as an ordered pair is (-2/3, -2)
40
40 - 5
40 +40 +20= 100%
5+5+2.5= 12.5 %
She gave 12.5 percent
