John mixed cashews and almonds. He bought 4 pounds of almonds for $22. The cost per pound for cashews is 60% more than the cost per pound of almonds.
John bought enough cashews that, when he mixed them with the almonds, the mixture had a value of $6.50 per pound.
Approximately what percent of the mixture, by weight, was cashews?
A) 20%
B) 25%
C) 30%
D) 35%

John bought 4 pounds of almonds for a total cost of $22.

almonds cost 22/4 = $5.50 per lb

----------------------------------

-The cost per pound for cashews is 60% more than the cost per pound for almonds.

1.6*5.5 = $8.80 per lb

-----------------------------------

-John bought enough cashews that, when he mixed them with the almonds, the mixture had a value of $6.50 per pound.

Approximately what percent of the mixture, by weight, was cashews?

Equation:

value + value = value

5.5a + 8.8c = 6.50(a+c)

5.5a + 8.8c = 6.5a + 6.5c

-----

1a = 2.3c

----

c = a/2.3

c = 0.435a

------

Total weight = a + c

Total weight = 1.435a

----

Percent of cashews = wt of cashews/total weight

Percent of cashews = 0.435a/1.435a = 38.3%

So, we simplify that...

It will be C) 30℅

Also, tell me if I'm wrong...

answer:   segregation violated the equal protection clause of the 14th amendment, which holds that no state can “deny to any person within its jurisdiction the equal protection of the laws.”

details/explanation:

brown v. board of education of topeka, decided by the us supreme court in 1954, ruled that all americans are entitled to the same civil liberties and protections in regard to access to education. until that decision, it was legal to segregate schools according to race, so that black students could not attend the same schools as white students.   an older supreme court decision, plessy v. ferguson (1896), had said that separate, segregated public facilities were acceptable as long as the facilities offered were equal in quality.   in the case of brown v. board of education, that standard was challenged and defeated.   segregation was shown to create inequality, and the supreme court unanimously ruled segregation to be unconstitutional.

the ruling was important in advancing civil rights because it affirmed that the 14th amendment applies to all rights and privileges of citizens, including access to   education.   this was being violated by states whose laws supported the segregation of schools.   section 1 of the 14th amendment reads as follows:
