Hood estimated that 12 trainees would take part in the program, with two intakes—one in the fall and one in the spring. Each course would involve around 50 hours of on-the-floor shadowing over three to four months. With an estimated price range of $300-$500 per participant, the potential revenue for each intake would be between $3,600-$6,000, assuming full enrollment of 12 trainees. Annually, this could result in $7,200-$12,000 in revenue. how do you know this calculation from the document
