you pay 9.70 for 2.5 pounds of roasted peanuts. You buy 1.4 pounds of almonds for 8.55 per pound.

How much less do roasted peanuts cost per pound than almonds?

How much more do you spend on almonds than on roasted peanuts.

$9.70 / 2.5lbs = $3.88 / pound of roasted peanuts.

$8.55 * 1.4lbs = $11.97 / 1.4 pounds of almonds

$8.55 - $3.88 = $4.67.

Roasted peanuts cost $4.67 less per pound than almonds.

$11.97 - $9.70 = $2.27

You spend $2.27 more on almonds than you do roasted peanuts.

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'.
