a chemist mixes one liter of pure water with x liters of a 60 % salt solution, and the resulting mixture is a 15 % salt solution. what is the value of x?	Choose one:
A) 1 / 4 B) 1 / 3 C) 1 / 2 D) 1 E) 3

a chemist mixes one liter of pure water with x liters of a 60 % salt solution, and the resulting mixture is a 15 % salt solution. what is the value of x?
divide(15, subtract(60, 15))
"concentration of salt in pure solution = 0 concentration of salt in salt solution = 60 % concentration of salt in the mixed solution = 15 % the pure solution and the salt solution is mixed in the ratio of - - > ( 60 - 15 ) / ( 15 - 0 ) = 3 / 1 1 / x = 3 / 1 x = 1 / 3 answer : b"
