Suppose we create a model to predict the average profit based on advertising budget and segment. There are three segments: A, B, and C, and the units of the variables profit and budget are dollars. Predicted average Profit = 50,000 + 1.2*(Advertising Budget) + 500(Segment B) - 300(Segment C) When the budget = $1,000, what is the overall predicted revenue? Question 21 options: $1,200 $50,000 $51,200 We are unable to answer this question with the model provided
