Explain how Egyptian commemorate the wealthy and royal dead and why

Well just to name a few things they did for the rich/wealthy would be

~Embalming (I don't remember 100% why they did this part sorry)

~They'd put belongings like food and other important stuff they had so they would have stuff in the afterlife.

They would embalm the rich to keep them looking good and healthy in the after life they would also bury them with many goods and sometimes pets for the after life also depending on the person they occasionally killed servants to send to the after life with them
