The intensity, Io, of a light source is reduced to I after passing through d meters of fog according to the formula I = Ioe−0.12d. If 1,200 lumens of light are present initially, what is an equivalent expression written as a percentage rate of lumens lost?

Hint: Find the value of e−0.12 on your calculator.

a) I = 1,200ed I = 1,200(0.887)d

b) I = 1,200e0.88d I = 1,200(0.88)d

c)I = 1,200ed I = 1,200(0.887)d

d)I = 1,200e0.88d I = 1,200(0.88)d
