Your local movie theater sent out promotional coupons for a $6 admission price to a new action movie that was just released. Without the coupon, the cost of admission is $10. Two hundred people attended the first screening of the day, and the total box office receipts for that screening were $1500. Choose the answer that best describes this situation. A. There is no solution to this system of equations. This is an impossible situation.
B. 125 people used the coupon, and 75 paid full price.
C. 100 people used the coupon, and 100 paid full price.
D. 75 people used the coupon, and 125 paid full price

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
