The intensity of sound, measured in decibels, can be modeled by I(d)=85−12log⁡10(d)I(d) = 85 - 12\log_{10}(d), where dd is the distance in meters from the sound source. According to this model, what happens to the sound intensity when the distance from the source increases from 10 meters to 100 meters?
