A sample contains a mixture of two dyes, A and B. The molar absorptivity coefficients for dye A are 4,875 at 628nm and 2,518 at 684 and for dye B are 1,578 at 628nm and 11,543 at 684nm. In an unknown mixture of the two dyes, the absorbance at 628nm is 0.7619 and the absorbance at 684nm is 0.6917. What are the concentrations of the two dyes?
