The percent of light that will pass through a material is given by the formula lgP = -kd, where P is the percent of light passing through the material (in fractions), k is a constant that depends on the material, and d is the thickness of the material in centimeters. The constant k for a piece of tinted glass is 0.4. How thick (in centimeters) is a piece of this glass that allows 50% of the light incident to the glass to pass through it? Round to the nearest hundredth of a centimeter.
a. 1.73 b. 0.75 c. 4.25 d. 9.78 e. 3.32
