You can put this solution on YOUR website!
The formula? Depends how you choose the variables.

Assuming concentrations are as percents,
H for the high concentration
L for the low concentration
v for how much of the high concentration material
u for how much of the low concentration material

C as percent of mixing the two,
highlight%28C=%28uL%2BvH%29%2F%28u%2Bv%29%29
