Answer:
(-1,3)
Step-by-step explanation:
Graph the given system of equations
y=-x+2
make a table for each equation to graph it
Lets assume some value for x and find out y
x y=-x+2
-1 -(-1) + 2= 3
0 0+2 = 2
1 -1+2 = 1
Now make a table for second equation
y= 4x+7
Lets assume some value for x and find out y
x y= 4x+7
-1 4(-1) + 7= 3
0 4(0) + 7 = 7
1 4(1) + 7 = 11
The graph is attached below
Solution is (-1,3)
Find the difference between prices: 4.86-4.50=.36
Divide the difference (.36) by the original price: .36/4.50=.08
