### Worked Examples Using Percentage Quantity Calculator

#### Example 1

If a class has 30 students and 20% of them are absent, how many students are absent?

Calculation

To find the percentage quantity, we multiply the total number of students by the percentage:

Recall the formula

q = b% * a/100

Where a = 30 students, b = the percentage of student absent

Hence,

30 x 20% = 30 x 0.20 = 6

Therefore, there are 6 students absent.

#### Example 2

If a recipe calls for 2 cups of flour and you want to use 75% of the recommended amount, how much flour should you use?

Solution

To find the percentage quantity, we multiply the recommended amount by the percentage:

Where a = 2 cups of flour, b = 75%

Using the formula

2 cups * 75%

= 2 cups x 0.75

= 1.5 cups

So, you should use 1.5 cups of flour.

#### Example 3

If a company's total revenue is $10,000 and 15% of it is profit, how much profit did the company make? Solution To find the percentage quantity, we multiply the total revenue by the percentage: Where a =$10,000, b = 15%

Hence,

$10,000 x 15% =$10,000 x 0.15

= $1,500 Hence, the company made a profit of$1,500.

#### Example 4

If a container can hold 500 ml of liquid and it is filled to 80% of its capacity, how much liquid is in the container?

Where a = 500 ml, b = 80%

Apply the percentage quantity formula

500 ml x 80%

= 500 ml x 0.80

= 400 ml

Final answer, there are 400 ml of liquid in the container.
