Answer:
10%
Step-by-step explanation:
Percentage increases is given by the formula:
![percentage \: increases = \frac{increases}{original \: value}](https://tex.z-dn.net/?f=percentage%20%5C%3A%20increases%20%3D%20%20%5Cfrac%7Bincreases%7D%7Boriginal%20%5C%3A%20value%7D%20)
Increases = $550 - $500 = $50
Original Value: $500
substitute the values into the formula
![percentage \: increases = \frac{50}{500} \times 100](https://tex.z-dn.net/?f=percentage%20%5C%3A%20increases%20%3D%20%20%5Cfrac%7B50%7D%7B500%7D%20%20%5Ctimes%20100)
= 10%
