Question statement

A chemist wishes to make $\var{Total}$ litres of $\var{CT}$ % acid solution.

She has at her disposal chemical A, which is $\var{CA}$ % acid, and chemical B, which is $\var{CB}$ % acid.

CB = $\var{CB}$

Find the volume of A and B needed.

Give any introductory information the student needs.

			Name	Type	Generated Value

A	integer	5
B	integer	7
Total	integer	12
CA	integer	6
CB	integer	11
CT	integer	7
