You are a small business owner preparing to launch your first ad campaign to attract new customers, and must decide whether to learn about advertising yourself or hire a professional to launch the campaign. The campaign will last three months. If you hire a professional, you'll have to pay them a lump sum of $1,200 for the entire campaign. But if you decide to do it yourself, you'll take a course that costs $200 to introduce you to the skill. You'll also pay an employee $320 per month to work some of the hours you normally work, while you manage the campaign. If you hire the professional, your total benefit would be all the money you avoid spending on doing the campaign yourself. What is the total benefit of hiring the professional?
