Here is the question as it follows:(adsbygoogle = window.adsbygoogle || []).push({});

The decibel scale, defined as

[tex] L = 10 log (\frac{I}{I_0}) [/tex]

where L is the Loudness (or comparative intensity) in decibels (dB),

[tex] I_0 [/tex] is the reference level (10^-12 watts per m^2)

I is the actual intensity of the sound measured (watts per m^2).

now heres the question part:

An owner of an industrial plant next to a residential suburb agreed to limit noise to 75dB with a variation of up to 15% at a distance of 100m from the factory gates. Residents subsequently complained that sounds often reached 85dB. The manager replied, "It's not far over the limit - it's under the 15% variation agreed." Discuss whether or not the mangers statement is justified.

Dont quite know what there getting at, any help would be greatly appreciated.
