Cookie 5 13 Summary

A boy gives a cookie to a mouse. The mouse asks for a glass of milk. He then requests a straw (to drink the milk), a mirror (to avoid a milk mustache), nail scissors (to trim his hair in the mirror), and a broom (to sweep up his hair trimmings). Cookies have been a topic of controversy for a number of months. The awareness of computer users about cookie files is increasing with media coverage and public discussion. While advertisers and privacy groups remain at odds over the potential value of cookies, they remain in wide usage.

Linear Programming

Solving systems of inequalities has an interesting application--it allows us to find the minimum and maximum values of quantities with multiple constraints.

First, assign a variable (x or y) to each quantity that is being solved for. Write an equation for the quantity that is being maximized or minimized (cost, profit, amount, etc.). This is that maximization or minimization equation. Next, write each constraint as an inequality. Number each inequality and graph the system, numbering each line on the graph as its corresponding inequality.

Plug the coordinates of the corners into the maximization/minimization equation. The coordinates that give the largest or smallest value for this equation (depending on what the problem is looking for) are the solution to the problem.

There are three quantities that we are often asked to maximize and minimize in linear programming problems. Revenue is the total amount of money taken in, cost is the total amount of money spent, and profit is the revenue minus the cost, or the total amount of money gained.

Example: Jimmy is baking cookies for a bake sale. He is making chocolate chip and oatmeal raisin cookies. He gets 25 cents for each chocolate chip cookie and 30 cents for each oatmeal raisin cookie. He cannot make more than 500 cookies of each kind, and he cannot make more than 800 cookies total. He must make at least one-third as many chocolate chip cookies as oatmeal raisin cookies. How many of each kind of cookie should he make to get the most money?
Variables:x = number of chocolate chip cookies (in hundreds)
y = number of oatmeal raisin cookies (in hundreds)
Maximization equation: Profit = 25x + 30y
Constraints:
1.x≤5
2.y≤5
3.x + y≤8
4.x≥y
Graph:
Corners:

1 and 3: x = 5, x + y = 8. (x, y) = (5, 3).
2 and 3: y = 5, x + y = 8. (x, y) = (3, 5).
2 and 4: y = 5, x = y. (x, y) = (, 5).

(5, 3)âá'Profit = 25(5) + 30(3) = 215.
(3, 5)âá'Profit = 25(3) + 30(5) = 225.
(, 5)âá'Profit = 25() + 30(5) = 191.67.
