Chapter 1.11, Problem 4E
A company produces Web design, software, and networking services. View the company as an open economy described by the accompanying table, where input is in dollars needed for $1.00 of output.
- a. Find the consumption matrix for the company.
- b. Suppose that the customers (the open sector) have a demand for $5400 worth of Web design, $2700 worth of software, and $900 worth of networking. Use row reduction to find a production
vector that will meet this demand exactly.

Suppose that a company needs 1,200,000 items during a year and that preparation for each production run costs $500. Suppose also that it costs $18 to produce each item and $3 per year to store an item.
Use the inventory cost model to find the number of items in each production run so that the total costs of production and storage are minimized.

Cost of a Hybrid Vehicle You may have wondered what the
break-even point is for purchasing a hybrid vehicle if you
paid in cash (no interest). Below is data for two models of
Honda Civic bases on $4.00 per gallon gas prices.

a. Find the cost function for each car, as a function of
miles driven x.
b. Determine the break-even miles. This represents the
number of miles you would need to drive the hybrid
before it becomes the cheaper alternative.
What is the maximum profit in this model?

- IKEA has a contract to deliver 100, 250, 190, 140, 220, and 110 home windows over the next 6 months. Production cost (labor, material, and utilities) per window varies by period and is estimated to be $50, $45, $55, $48, $52, and $50 over the next 6 months. To take advantage of the fluctuations in manufacturing cost, IKEA can produce more windows than needed in a given month and hold the extra units for delivery in later months. This will incur a storage cost at the rate of $8 per window per month, assessed on the end-of season inventory. Now IKEA wants to minimize their respective cost. Based on this data answer the following questions Qus.1)Write down the objective function of the linear programming consistent with the objective of IKEA.arrow_forwardThe manager of the customer service department at a bank can hire employees with a high school degree (HS) who earn $10,000 annually or employees with a bachelor's degree (B) who earn $20,000.
