The cost, in millions of dollars, of building a three-story high school in New York State was estimated to be C(x) = 1.7 + 0.16x − 0.0001x2 (20 ≤ x ≤ 400)
where x is the number of thousands of square feet. Suppose that you are contemplating building a for-profit three-story high school and estimate that your total revenue will be $0.2 million dollars per thousand square feet. What is the profit function (in millions of dollars)?
