FWIW.
The drug dealers and gang members on the urban streets of America have a better understanding of both math and economics than almost any academic tool for social justice.
Math Problem: Tyrone bought an OZ of coke for $2000, and cuts it 50% with inositol, and sells it for $100 per gram, if Tyrone wants to buy two new Nines for $1000, how many lap dances can he buy at the strip club Friday at $50 per dance?
I guarantee Tyrone knows the answer to this question.
