The Richter scale converts seismographic readings into numbers for measuring the magnitude of an earthquake according to this function M(x) = log 
, where x0 = 10-3.Two earthquakes differ by 0.1 when measured on the Richter scale. How would the seismographic readings differ at a distance of 100 kilometers from the epicenter?
A. The earthquake of greater magnitude has a seismographic reading that is 
times that of the lesser earthquake.
B. The earthquake of greater magnitude has a seismographic reading that is 100 times that of the lesser earthquake.
C. The earthquake of greater magnitude has a seismographic reading that is 10 times that of the lesser earthquake.
D. The earthquake of greater magnitude has a seismographic reading that is 
times that of the lesser earthquake.
