Chapter 3: Problem 53

Resource Allocation You manage an ice cream factory that makes three flavors: Creamy Vanilla, Continental Mocha, and Succulent Strawberry. Into each batch of Creamy Vanilla go two eggs, one cup of milk, and two cups of cream. Into each batch of Continental Mocha go one egg, one cup of milk, and two cups of cream. Into each batch of Succulent Strawberry go one egg, two cups of milk, and one cup of cream. Your stocks of eggs, milk, and cream vary from day to day. How many batches of each flavor should you make in order to use up all of your ingredients if you have the following amounts in stock? a. 350 eggs, 350 cups of milk, and 400 cups of cream b. 400 eggs, 500 cups of milk, and 400 cups of cream c. \(A\) eggs, \(B\) cups of milk, and \(C\) cups of cream

Short Answer

Expert verified
For case a (350 eggs, 350 cups of milk, 400 cups of cream), after solving the system of equations, we get \(x = 50\), \(y = 100\), and \(z = 100\). Thus, you should make 50 batches of Creamy Vanilla, 100 batches of Continental Mocha, and 100 batches of Succulent Strawberry. For case b (400 eggs, 500 cups of milk, 400 cups of cream), after solving the system of equations, we get \(x = 50\), \(y = 100\), and \(z = 150\). Thus, you should make 50 batches of Creamy Vanilla, 100 batches of Continental Mocha, and 150 batches of Succulent Strawberry. For case c (\(A\) eggs, \(B\) cups of milk, and \(C\) cups of cream), the number of batches for each flavor will depend on the specific values of A, B, and C. Solve the system of equations using the given values to find the required number of batches of each flavor.

Step by step solution

01

Define Variables

Let \(x\) be the number of Creamy Vanilla batches, \(y\) be the number of Continental Mocha batches, and \(z\) be the number of Succulent Strawberry batches. Step 2: Set up the equations based on the ingredient requirements
02

Set Up Equations

We can set up a system of three linear equations based on the ingredients: 1. Eggs equation: \(2x + y + z = E\) 2. Milk equation: \(x + y + 2z = M\) 3. Cream equation: \(2x + 2y + z = C\) where \(E\) is the number of eggs, \(M\) is the number of cups of milk, and \(C\) is the number of cups of cream. Step 3: Solve the system of equations for each given set of ingredients
03

Solve the System of Equations

Substitute the stock values for eggs, milk, and cream in the equations and solve for \(x\), \(y\), and \(z\) for each case: a. 350 eggs, 350 cups of milk, and 400 cups of cream: Eggs equation: \(2x + y + z = 350\) Milk equation: \(x + y + 2z = 350\) Cream equation: \(2x + 2y + z = 400\) b. 400 eggs, 500 cups of milk, and 400 cups of cream: Eggs equation: \(2x + y + z = 400\) Milk equation: \(x + y + 2z = 500\) Cream equation: \(2x + 2y + z = 400\) c. \(A\) eggs, \(B\) cups of milk, and \(C\) cups of cream: Eggs equation: \(2x + y + z = A\) Milk equation: \(x + y + 2z = B\) Cream equation: \(2x + 2y + z = C\) In each case, solve the system of equations to find the number of batches of each flavor (\(x\), \(y\), and \(z\)), ensuring all ingredients are used up. This can be done using methods such as substitution, elimination, or matrices. Note that the solution may not yield integer values for \(x\), \(y\), and \(z\), which may mean it is not possible to use the exact amounts of ingredients to make the desired ice cream flavors.

Australia Economy \(^{34}\) Two sectors of the Australian economy are (1) community services and (2) recreation services. The 1978-79 input-output table involving these two sectors results in the following value for \((I-A)^{-1}\) : $$ (I-A)^{-1}=\left[\begin{array}{ll} 1.0066 & 0.00576 \\ 0.00496 & 1.04206 \end{array}\right] $$ Complete the following sentences. a. \(0.00496\) additional dollars worth of \(\quad\) must be produced to meet a \(\$ 1\) increase in the demand for b. additional dollars worth of community services must be produced to meet a one-dollar increase in the demand for community services.

Find: (a) the optimal mixed row strategy; (b) the optimal mixed column strategy, and (c) the expected value of the game in the event that each player uses his or her optimal mixed strategy. $$ P=\left[\begin{array}{rr} -1 & 0 \\ 1 & -1 \end{array}\right] $$

Describe a situation in which a both a mixed strategy and a pure strategy are equally effective.

Your market surveys show that Brakpan and Nigel each provide a potential market of 2,000 burgers a day, while Springs provides a potential market of 1,000 burgers per day. Your company can finance an outlet in only one of those cities. Your main competitor, Burger Princess, has also obtained licenses for these cities, and is similarly planning to open only one outlet. If you both happen to locate at the same city, you will share the total business from all three cities equally, but if you locate in different cities, you will each get all the business in the cities in which you have located, plus half the business in the third city. The payoff is the number of burgers you will sell per day minus the number of burgers your competitor will sell per day.

If \(A\) and \(B\) are invertible, check that \(B^{-1} A^{-1}\) is the inverse of \(A B\).
