How is Plessy vs. Fergusson related to Brown vs. Board of Education of Topeka, Kansas?

In Plessy v. Ferguson, the court ruled that seperate but equal is legal.

In Brown v. The Board of Education, the court ruled that there would be no segregation within schools.

Therefore, one difference between the two was that in Brown v. The Board of Education, Linda Brown got something out of the trial, Plessy did not get anything out of Plessy v. Ferguson.  

Another difference could be that they were both in different decades. Plessy took place in 1892, and Brown took place in 1954.

Some similarities include:

Both took their cases to the U.S. Supreme Court, & both were fighting for rights listed under the 14th amendment.

hope this helps plz brianlest me

i think it can have both positive and negative effects on businesses.

for example:

lets say you own a small business and taxes go up 4% that means it is going to cost your business more money to buy product to sell. but at the same time you make more money from the tax rise.

that is my theory.
