Felix has saved $30 per week to buy a new blu-ray player. he compares two different models: a panaview that is priced at $130 and a zony model that is priced at $140. felix decides to purchase the zony blu-ray player for $140.

identify what role money plays in each of the following parts of the story.
1. felix can easily determine that the panaview model has a lower price than the zony model.
2. felix saved $30 per week.
3. felix pays $140 for the blu-ray player.
1. unit of account
2. store of value
3. medium of exchange

1. Felix can easily determine that the panaview model has a lower price = Value of money

2. Felix saved $30 per week = Resource gathering

3. Felix pays $140 for the Blu-Ray = Medium of exchange

Step-by-step explanation:

1. The price of each blu-ray is notices by Felix as he can easily see the value and compare prices to drive his decision

2. The resource's needed to for obtaining the value which Felix desired is gathered.

3. Exchange of money for desired value or valuable

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'.
