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

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
