if 20 liters of chemical x are added to 80 liters of a mixture that is 15 % chemical x and 85 % chemical y, then what percentage of the resulting mixture is chemical x? Pick:
A) 30 %
B) 32 %
C) 35 %
D) 38 %
E) 40 %

if 20 liters of chemical x are added to 80 liters of a mixture that is 15 % chemical x and 85 % chemical y, then what percentage of the resulting mixture is chemical x?
add(20, multiply(divide(15, const_100), 80))
"the amount of chemical x in the solution is 20 + 0.15 ( 80 ) = 32 liters . 32 liters / 100 liters = 32 % the answer is b ."
