Answer:
Howie should do the following to maximize income:
Write articles specifically targeted to high-school and college-aged individuals
For example, he could write about student loan debt and the nature of them, or about which majors are the most profitable taking into account average earnings after graduation, and deducting student loan expenses from those earnings.
Promote ads that target the age group
He could gain revenue from college ads, textbooks companies ads, or even banks, because his target age group are starting to get things such as loans or credit cards.
Try to interact as often as possible with the reader
Young people like interaction, and the topic of personal finance might be complicated and overwhelming for a young person. He should allow commentary in every one of the articles, and try to answer as many commentaries as possible.
