An old metal worker has a side business making outdoor barbecue grills. He purchases scrap metal at 87/100 per hundred pounds, and makes out of it grills weighing 350 pounds each, which he sells at $255.42.How much profit does he gain on each 100 pounds of scrap metal?

im gona guess at 10$ A POUND

Step-by-step explanation:

Currently, the closest scrap yard to me pays $195 per ton, or per 2,000 pounds for ferrous metals. This breaks down to approximately $10 per 100 pounds of metal. The price that scrap yards pay fluctuates with worldwide supply and demand and can change daily.

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'.
