Question 867277
Consider the equation {{{L = .87x}}}, which gives the percent of light that will pass through x thicknesses of a certain type of tinted glass. (L = lumens per square meter).
------------
Using your equation:
L = 0.87*6 = 5.22
==============
{{{L = 0.87^x}}} is more likely
L =~ 0.434
= 43.4%
