CALCULATING THE AMOUNT OF A DISCOUNT LESSON PLAN
Percentages are used all the time when we are working with money. Often when we calculate percentages with money, we look for the amount of a percentage when using a purchase price. We can call this the percent of a number.
How can we calculate the percent of a number?
Let’s begin by looking at an example. Then we can apply this information to working with money.
Example: What is 32% of 25?
To calculate this number, we are looking for a part of 25. We actually want to specifically find 32% of 25. To do this, we can use our key words to help us.
One key word is the word “of”- the word “of” means to multiply. What is- means an unknown and then an equal sign.
Here is the first part of the equation that we are going to write.
This is the first part of the problem the “what is” part.
Next, we work with the 32% of 25.
If “of” means multiply then we have the next part of the equation.
