Hey there! As far as I understand the problem, she made $2,200 in profit. Take 1,375 and multiply it by 1.6.
Y=-x/2+9
y=x+7
If we solve this system of equations, we can find the solution to the following system of equation.
we can solve this system of equation by equalization method.
-x/2+9=x+7
lowest common multiplo=2
-x+18=2x+14
-3x=-4
x=-4/-3=4/3
y=x+7=4/3 + 7=(4+7*3)/3=25/3
The solution is (4/3, 25/.3)
answer: Line y=-x/2+9 intersects line y =x+7
