In this problem, we need to apply systems of equations to buying Cat Trees.

We are given to companies with different conditions, so we can write these equations.

Part [A]

One company, PP, offers the following deal:

- $100 for the cat tree,

- and $50 for each additional part or toy.

The second company, MN, offers this deal:

- $50 for a basic cat tree

- $75 for each additional part

For both companies, let x represent the additional pieces and y represent the total cost. Then we get


\begin{gathered} \text{ PP}:y=50x+100 \\ \\ \text{ MN}:y=75x+50 \end{gathered}

Part [C]

One way to solve this system is by graphing the equations. We can do this by creating a simple table for each function, then graph the points. Which numbers this large, a table is the better way to go.

Let's begin with the company PP:


y=50x+100

A simple table gives us

Graphing those points, we have:

Next, we move on to the company MN:


y=75x+50

We can create a similar table and graph it on the same coordinate plane.

Part [D]

Finally, we want to talk about someone trying to decide the best place to purchase the cat tree depending on how many add-on's he want to buy.

Based on the graph, we see that the cat trees will cost the same if he buys 2 add-ons.

If he chooses to buy less than 2 add-ons, the MN company wil give the cheaper prices (in blue).

If he wants to buy more than 2 add-ons, the PP company will get him the cheaper overall cost.
