1. The problem statement, all variables and given/known data 2. Relevant equations none 3. 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. Thanks.
