Answer:
[tex]\%Increase = 25\%[/tex]
Step-by-step explanation:
Given
[tex]Last\ Year = 120[/tex]
[tex]This\ Year = 150[/tex]
Required
Determine the percentage increase
This is calculated as thus:
[tex]\%Increase = \frac{This\ Year - Last\ Year}{Last\ Year} * 100\%[/tex]
[tex]\%Increase = \frac{150 - 120}{120} * 100\%[/tex]
[tex]\%Increase = \frac{30}{120} * 100\%[/tex]
[tex]\%Increase = 0.25 * 100\%[/tex]
[tex]\%Increase = 25\%[/tex]
