Subtract the sale price from the original price then divide the difference by the original price.
Guitar 1: 160 -100 = 60
60/160 = 0.375 x 100 = 37.5%
Guitar 2: 250 - 150 = 100
100/250 = 0.4 x 100 = 40%
The answer is the second guitar has a greater percent change of approximately 40%

X=-4y+2
3(-4y+2)+2y=11
-12y+6+2y=11
-10y+6=11
-6=-6
-10y=5
y=-1/2
3x+2(-1/2)=11
3x-1=11
+1=+1
3x=12
x=4
Solution:(-1/2,4)
We have been given the equation
![y=-5.131x^2+31.821x-3.333](https://tex.z-dn.net/?f=y%3D-5.131x%5E2%2B31.821x-3.333)
It represents the number of people standing to catch a commuter train x hours after 5 A.M.
Now, in order to find the number of people in line at 7 a.m. , we need to substitute x= 2 in the above equation.
![y(2)=-5.131(2)^2+31.821(2x)-3.333\\y(2)= 39.785 \approx 40](https://tex.z-dn.net/?f=y%282%29%3D-5.131%282%29%5E2%2B31.821%282x%29-3.333%5C%5Cy%282%29%3D%2039.785%20%5Capprox%2040)
Therefore, the number of people in the line at 7 a.m. is 40
