**Finding percent increase worksheet:**

Worksheet on finding percent increase is much useful to the students who would like to practice problems on finding increment of a quantity in percentage.

The formula given below can be used to find how an amount changes in terms of percentage.

The change may be an increase or a decrease. Percent increase describes how much a quantity increases in comparison tothe original amount.

1. What is the percent increase from $5 to $8 ?

2. Amber got a raise, and her hourly wage increased from $8 to $9.50. What is the percent increase ?

3. The price of a pair of shoes increases from $52 to $64. What is the percent increase to the nearest percent ?

4. In a class, students strength has been increased from 20 to 30. What percent of strength is increased ?

5. Mr. David monthly salary is revised from $2500 to $2600. What percentage is the salary increased ?

**Problem 1 : **

What is the percent increase from $5 to $8 ?

**Solution :**

**Step 1 :**

Find the amount of change.

Amount of change = Greater value - Lesser value

= 8 - 5

= 3

**Step 2 : **

Percentage change is

= (Amount of change / Original amount) x 100 %

= (3 / 5) x 100%

= 0.6 x 100 %

= 60 %

Hence, the percent increase from $5 to $8 is 60%.

**Problem 2 : **

Amber got a raise, and her hourly wage increased from $8 to $9.50. What is the percent increase?

**Solution :**

**Step 1 :**

Find the amount of change.

Amount of change = Greater value - Lesser value

= 9.50 - 8.00

= 1.50

**Step 2 : **

Find the percent increase. Round to the nearest percent.

Percentage change is

= (Amount of change / Original amount) x 100 %

= (1.50 / 8.00) x 100%

= 0.1875 x 100 %

= 18.75 %

**≃ **19 %

Hence, Amber's hourly wage is increased by 19%.

**Problem 3 : **

The price of a pair of shoes increases from $52 to $64. What is the percent increase to the nearest percent?

**Solution :**

**Step 1 :**

Find the amount of change.

Amount of change = Greater value - Lesser value

= 64 - 52

= 12

**Step 2 : **

Find the percent increase. Round to the nearest percent.

Percentage change is

= (Amount of change / Original amount) x 100 %

= (12 / 52) x 100%

= 0.2307 x 100 %

= 23.07 %

**≃ **23 %

Hence, the price of a pair of shoes increased by 23%.

**Problem 4 : **

In a class, students strength has been increased from 20 to 30. What percent of strength is increased ?

**Solution :**

**Step 1 :**

Find the amount of change.

Amount of change = Greater value - Lesser value

= 30 - 20

= 10

**Step 2 : **

Find the percent increase. Round to the nearest percent.

Percentage change is

= (Amount of change / Original amount) x 100 %

= (10 / 20) x 100%

= 0.5 x 100 %

= 50 %

Hence, the strength is increased by 50%.

**Problem 5 : **

Mr. David monthly salary is revised from $2500 to $2600. What percentage is the salary increased ?

**Solution :**

**Step 1 :**

Find the amount of change.

Amount of change = Greater value - Lesser value

= 2600 - 2500

= 100

**Step 2 : **

Find the percent increase. Round to the nearest percent.

Percentage change is

= (Amount of change / Original amount) x 100 %

= (100 / 2500) x 100%

= 0.04 x 100 %

= 4 %

Hence, David's monthly salary is increased by 4%.
