# Tyrone's Cocaine Factory

Calculus Level 3

Tyrone operates a trap that produces crack and sells each gram of dope at $$10x$$ its mass in grams. If his revenue can be modeled by the function $$r(x) = 10x$$ where $$x$$ is the number of grams, and the function is in terms of hundreds of dollars. Tyrone's chefs have a function that calculates the cost of operating the trap: $$c(x) = x^3 - 6x^2 + 15x$$

How many grams should Tyrone cook in order to make the most profit?
