a mixture conntains two compound that absorbs strongly in the 300-600nm range the molar absorptivities of the two compounds at two wavelenghts in this range are shown in the table compound molar absorptivity at 400 nm molar absorptivity at 500 nm

A 11,000 2200
B 1200 8700

The absorbance of the mixture is measured at these two wavelenght and is found to be 0.232 at 400 nm and 0.131 at 500 nm. what is the concentration of A and B in the mixture?
