Question details

The cost, in millions of dollars, of building a three-story high school in New York State was estimated to be

C(x) = 2.2 + 0.13x − 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 $0.17 million dollars per thousand square feet. What is the profit function (in millions of dollars)?

P(x) =



What size school should you build to break even? (Round your answer to three decimal places.)

thousand ft2

2, Find a linear equation whose graph is the straight line with the given properties. HINT [See Example 2.]

Through

(20, −9.2)

and increasing at a rate of 7 units of y per unit of x.

y(x) =

The following table shows worldwide sales of a certain type of cell phone and their average selling prices in 2012 and 2013.

Year 2012 2013
Selling Price ($) 385 315
Sales (millions) 827 1,219

(a) Use the data to obtain a linear demand function for this type of cell phone. (Let p be the price, and let q be the demand).

q(p) =


3, Use your demand equation to predict sales if the price is lowered to $285.
million phones

(b) Fill in the blank.

For every $1 increase in price, sales of this type of cell phone decrease by  million units.
