Systems of Equations Word Problems
By yourteachermathhelp
For a complete lesson on systems of equations word problems, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to solve number and value word problems using a system of linear equations, as demonstrated in the following problem. Rodolfo has a total of 17 dimes and quarters worth $3.05. How many of each coin does he have? The two variables used in this problem are d, number of dimes, and q, number of quarters. Since Rodolfo has a total 17 dimes and quarters, one equation is d + q = 17. Since the value of his coins is $3.05, the other equation is 10d + 25q = 305. Note that since d represents the number of dimes, 10d represents the value of the dimes. And since q represents the number of quarters, 25q represents the value of the quarters.

Maximum and Minimum Value Word Problems - Quadratic Equations
By The Organic Chemistry Tutor
This algebra video tutorial explains how to solve word problems that asks you to calculate the maximum value of a function or the minimum value of a quadratic equation. The first problem asks you to determine the number of items a company must produce / sell to maximize the profit. The second question asks you to determine how long it takes for a ball to reach its maximum height as well as determine the maximum height. This is a typical projectile motion problem found in physics.
