____________________________________________________________________
A. 2 times stronger
B. 1000 times stronger
C. 100 times stronger
D. 20 times stronger

Answer 1

100 stronger

Step-by-step explanation:

Answer 2

the 7.5 is a 100 times stronger than the 5.5 . The 100 comes from the increase in scale from 5.5 to 7.5 which is an increase of two so you multiply the strength of the weaker earthquake 10^7-5=10^2=100 and that gives you the strength of the stronger earthquake!
