A freelance writer must choose how to spend her time working on several different types of projects. Newspaper stories (N) take 3 hours to write and pay a flat rate of $45 per story. Magazine articles (M) take much longer to write (25 hours) but pay significantly better ($400 per article). Proofreading academic articles (P) takes on average 10 hours each article but pays $600 per article. The writer wants to maximize her income but doesn't want to work more than 60 hours per week. Additionally, she dislikes proofreading so she would like to spend no more than 30 hours per week on that task. What is the optimal mix of jobs for the writer to accept each week?
