The loudness, $\displaystyle {L}$, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, $\displaystyle {d}$, from the source of the sound.

A person 10 feet from a jetski, it is 85 decibels loud.

How loud is the jetski when the person is 44 feet away? (Round to 3 decimal places.)
