Once the problem is read, you need to list all the components and data that are involved. When you devise a plan (translate), you come up with a way to solve the problem.
Setting up an equation, drawing a diagram, and making a chart are all ways that you can go about solving your problem.
In this tutorial, we will be setting up equations for each problem.
You will translate them just like we did in Tutorial 2: Algebraic Expressions and Tutorial 5: Properties of Real Numbers. This is where you solve the equation you came up with in your 'devise a plan' step.
Even the best athletes and musicians had help along the way and lots of practice, practice, practice, to get good at their sport or instrument. If the couch you have our eye on is $440 after the markdown, what was the original price?
To get the most out of these, you should work the problem out on your own and then check your answer by clicking on the link for the answer/discussion for that problem. How much would you save if you bought it at this sale?A lot of numeric types of word problems revolve around translating English statements into mathematical ones.If you need a review on these translations, you can go back to Tutorial 2: Algebraic Expressions and/or Tutorial 5: Properties of Real Numbers.That's what it also takes to be good at problem solving.George Polya, known as the father of modern problem solving, did extensive studies and wrote numerous mathematical papers and three books about problem solving.Polya created his famous four-step process for problem solving, which is used all over to aid people in problem solving: Sometimes the problem lies in understanding the problem.If you are unclear as to what needs to be solved, then you are probably going to get the wrong results.The equations in this tutorial will all be linear equations.If you need help solving them, by all means, go back to Tutorial 7: Linear Equations in One Variable and review that concept.Whenever you are working with a percent problem, you need to make sure you write your percent in decimal form.You do this by moving the decimal place of the percent two to the left.
