When one person shouts at a football game, the sound intensity level at the center of the field is 59.0 dB. When all the people shout together, the intensity level increases to 100 dB. Assuming that each person generates the same sound intensity at the center of the field, how many people are at the game?

use the property of logs:
log(n*a) = log(n) + log(a)
You have n*a and a.
