On a certain scale of intensity, each increment of 10 in magnitude represents a tenfold increase in intensity. On this scale, an intensity corresponding to a magnitude of 165 is how many times an intensity corresponding to a magnitude of 125?
(A) 40
(B) 100
(C) 400
(D) 1,000
(E) 10,000
ANS is E
I guess I am having trouble understanding the the setup, can someone help?

If each increment of 10 in magnitude represents a tenfold increase in intensity, then:
165 - 125 = 40
10^4 = 10,000
165 - 125 = 40
10^4 = 10,000
