Hey, lucky you, we have another tutorial on word problems.As mentioned before, whether you like it or not, whether you are going to be a mother, father, teacher, computer programmer, scientist, researcher, business owner, coach, mathematician, manager, doctor, lawyer, banker (the list can go on and on), problem solving is everywhere.In this tutorial, we will be setting up equations for each problem.
Hey, lucky you, we have another tutorial on word problems.
To be solved, a word problem must be translated into the language of mathematics, where we use symbols for numbers - known or unknown, and for mathematical operations.
When all is said and done, a word problem, stripped from inessential details, translates into one or more mathematical equations of one kind or another.
In order to show an understanding of the problem you of course need to read the problem carefully.
Sounds simple enough, but some people jump the gun and try to start solving the problem before they have read the whole problem.
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.
At the link you will find the answer as well as any steps that went into finding that answer. A student has money in three accounts that pay 5%, 7%, and 8%, in annual interest.
After the equations have been solved, the result can be translated back into the ordinary language. Mathematical formulation contains only what is important in a problem.
But how does one know what is important and what is not, what is essential and what can be dispensed with?
When the plane is with the wind, it will be going faster.
That rate will be Since the break-even point is when revenue = cost, we will go right into setting this up using the substitution method as discussed in Tutorial 19: Solving Systems of Linear Equations in Two Variables.
