## How Do You Solve a Standard Minimization Problem? In an earlier post, we wrote out a standard minimization problem from an application. Now we’ll solve that problem by finding the dual standard maximization problem and applying the Simplex Method.

This process is covered in Section 4.4 of the textbook. For complete details on the process, consult this section and the many examples contained in this section. I will assume that you have looked over this section and are familiar with carrying out row operations on a matrix.

## How Do You Write Out a Standard Minimization Problem? Let’s take a look at a problem that requires a bit of ingenuity to put into standard minimization form.

Problem – Garton’s Seeds has a seed mixture containing three types of seeds: bluegrass, rye, and Bermuda. The cost per pound of the three seeds are 16 cents, 14 cents and 12 cents. Bluegrass seed must be at least 25% of the each batch. The amount of Bermuda must be no more than 2/3 the amount of rye in each batch. To fill current orders, Garton’s must make at least 6000 lbs of the mixture. How many pounds of each seed should be in the batch so that the cost of the batch is minimized?

## Make a Table of Values in Google Sheets

Suppose you want to generate a table of values from a formula…perhaps to help evaluate a limit. Google Sheets (or any spreadsheet) can quickly generate the values.

## Logarithms and the Compound Interest Formula

You can solve for any constant in the compound interest formula In an earlier FAQ, we looked at solving for the rate r. In the FAQ below, we look at how logarithms can be used to solve for the number of years, n, in the power.
