How are percent transmittance and absorbance related algebraically?

So, if all the light passes through a solution without any absorption, then absorbance is zero, and percent transmittance is 100%. If all the light is absorbed, then percent transmittance is zero, and absorption is infinite.

Absorbance is the inverse of transmittance so,

A = 1/T

Beer's law (sometimes called the Beer-Lambert law) states that the absorbance is proportional to the path length, b, through the sample and the concentration of the absorbing species, c:  

A ∝ b · c

As Transmittance,

% Transmittance,

Absorbance,

Hence, is the algebraic relation between absorbance and transmittance.
