Ihave an algebra question i can't quite figure it out. can anyone ?
a chemist has a 30% and a 45% acid solution. what amount of each solution should be used to make 500ml of solution with 35% acidity?
a) 133 1/3ml of 30% solution and 366 2/3ml of 45% solution
b) 250 ml of each solution.
c) 333 1/3 ml 30% solution and 166 2/3 ml of 45% solution
d) 400 ml of 30% solution and 100 ml of 45% solution

by the way, the 1/3 and 2/3 are fractions.
