Applications
In this lesson, we’ll take a look at some word problems.
Before working these problems,
it is helpful to have a strategy to use to solve.
Step 1:
Read the problem until you understand what you are being asked to find.
Step 2:
If the problem mentions a geometric shape, such as a rectangle or a circle, draw
the shape.
Step 3:
Define the variable, and write it down.
Use the definition of the variable to
define other quantities, if you can.
Step 4:
Write an equation, and then solve it.
Step 5:
Look back at the problem and make sure you answer the question that was
posed.
For each of the examples, write an appropriate equation to model the situation, then solve
the equation and answer the question that was posed.
