At the Pizza Dude restaurant, a 12-in. pizza costs 5.40 to make, and the manager wants to make at least 4.80 from the sale of each pizza. If the pizza will be sold by the slice and each pizza is cut into 6 pieces, what is the minimum charge per slice?
1. After an aggressive marketing campaign in the local community, Lumyn Electronics discovered that their cost can now be modeled by the equation: C(n) = 25n2 - 1,500n + 25,000, where n represents the number of TV remote controls sold in a particular month.a) How many TV remote controls must be sold in a month in order to minimize the company's cost?b) What is that minimum cost?
A researcher in physiology has decided that a good mathematical model for the number of impulses fired after a nerve has been stimulated is given by y=−x2+40x−50, where y is the number of responses per millisecond and x is the number of milliseconds since the nerve was stimulated. (a) When will the maximum firing rate be reached? (b) What is the maximum firing rate?
Farmer Jones, and his wife, Dr. Jones, decide to build a fence in their field, to keep the sheep safe. Since Dr. Jones is a mathematician, she suggests building fences described by y=8x^2 and y=8x^2 and y=x^2+11 and y=x^2+11. Farmer Jones thinks this would be much harder than just building an enclosure with straight sides, but he wants to please his wife. What is the area of the enclosed region?
Suppose the cost per hour incurred in operating a cruise ship is 5a + b^4v^3 dollars per hour, where a and b are positive constants and v is the ship's speed in miles per hour. At what speed (in miles per hour) should the ship be operated between two ports, at a distance D miles apart, to minimize the cost? (Hint: Minimize the cost, not the cost per hour.) V = _______mph
Suppose the labor cost (in dollars) for manufacturing a camera can be approximated by L(x,y)=3x2/2+y2−8x−8y−2xy+203 where x is the number of hours required by a skilled craftsperson and y is the number of hours required by a semiskilled person. Find values of x and y that minimize the labor cost. Find the minimum labor cost.

The manager of Dixie Furniture Company estimates that the daily output of her factory (in thousands of dollars) Q is given by Q = 4x1/4y3/4 where x is the amount spent on labor and y is the amount spent on capital (both measured in thousands of dollars). (a) Find the daily output of the factory if $16,000 is spent on labor and $256,000 is spent on capital each day. $ (b) Suppose that the output of the factory is to be maintained at the level found in part (a). By how much should the amount spent on capital be changed if the amount on labor is increased by $1,000? (Use the differential to calculate the answer. Round your answer to the nearest cent.) $ What is the MRTS? (Round your answer to the nearest cent.) $ per thousand dollars
