Simple Math


Cyrus is a drug dealer who specializes is selling crack cocaine (substance A) to high school students. Cyrus usually sells his crack uncut to keep his clientele happy, but he is behind on his monthly Escalade payments and needs to collect additional capital as soon as possible. Because of these circumstances, he decides to cut substance A with substance B. By blending substances A and B, the resulting substance C in created. The resultant weight of substance C is 10 percent greater than substance A. If Cyrus makes a 50 percent return on investment selling substance A, what was his initial investment in substance A if substance C sells for $1000?

a) $1011
b) $909
c) $606
d) $667
e) $505

Putting my name out there. Hope I'm right!

A = uncut crack
C = cut crack


1.1a = c
c = 1000
1.1a = 1000
a = 909
1.5x = 909
x = 606

ANSWER: C: 606
