# Relationship between solution and corresponding graph

none

## The Attempt at a Solution

Here is my answer for part A of this question:

Part B:
This is where I am having trouble.

I took a guess at this, but it is probably completely wrong:

The corresponding graph shows the profit when different amounts are spent. The x-intercepts show the amount spent when the profit is $0. I get this is most likely wrong, so can someone please explain to me the relationship between the graph and my solution? or at least lead me in the right direction to forming an answer.

Why would you think it is wrong? It looks 100% correct to me.

Okay, I just took a guess for part b, and wrote the first thing I saw when I looked at the graph, I didn't think it was correct :/

Anyway, thanks for verifying my answer
