Original Income = 15,000
New income = 20,000
The percentage Increase in the income can be calculated as:
[tex] \frac{Change}{Original} * 100[/tex]%
The change in income = 20000 - 15000 = 5000
Using the values, we get:
[tex] \frac{5000}{15000}*100 [/tex]%
= [tex]33.33[/tex]%
This means, Pats income increased by 33.33% in a period of ten years
