Example Question #1 : Solving Linear Equations With Part, Percent, And Whole
If 
First, we will need to convert 
Now, the word "of" means we will need to multiply 0.05 by our unknown number, 
Now, divide both sides by 0.05
Example Question #2 : Solving Linear Equations With Part, Percent, And Whole
If 
To be able to write the question as an equation, we need to first convert 
Now, we can write the following equation and solve.
Example Question #3 : Finding Part, Percent, And Whole
Jimmy is a salesman who is paid a base salary of 
We can write the following equation to represet Jimmy's salary:
Because we know Jimmy sold $1920 this month, we can plug it into the above equation.
Now, convert the percent into a decimal to find how much Jimmy made this month.
Example Question #17 : Percents And Decimals
If 
First, we need to convert 
Then, we can write the following equation using the information given in the question:
where 
Now, solve for
Example Question #2 : Solving Linear Equations With Part, Percent, And Whole
When an unknown number is increased by 
First, convert the percent into a decimal.
Now, increasing an unknown number by 
Next, set that equal to 88, since that is what the question tells us to do.
Now solve.
Example Question #2 : Solving Linear Equations With Part, Percent, And Whole
Before we can write an equation, we need to turn the percent into a decimal.
Now, we can write the following equation:
Divide both sides by 
Example Question #1 : Solving Linear Equations With Part, Percent, And Whole
If 
First, let 
Then, let's convert the percentage 
Translating the question above into an equation, we have:
Dividing both sides by 
Example Question #4 : Solving Linear Equations With Part, Percent, And Whole
If 
First, let's convert the percentage 
Then, translate the above question into an equation:
Dividing by
