Solve the application problems of linear function.

(1). Sweet Delight Candies, Inc., has daily fixed costs from salaries, rent, and other operations of $300. Each

pound of candy produced costs $1 and is sold for $2. Find the cost function, the revenue function, and

the break-even point.

(2). The market price for certain product is $5.00 per unit and occurs when 14,000 units are produced. At a

price of $1, no units are manufactured and, at a price of $19.00, no units will be purchased. Find the

supply and demand equations, assuming they are linear.
