The relationship between quantities m and n is expressed by the equation 30m = 5(n - 42). If the difference between the two chosen values of n is 30, what is the difference in the corresponding values of m?  Pick one.
A) 5  B) 42/11  C) 60/11  D) 150/11  E) 14
5nother Simple way   30m=5(n-42)   5ssume n = 42 to make one side equal to 0   then 30m=0   and m = 0   Repeat it by assuming n as 42+30 i.e 72   30m- 5(72-42)   30m=150   m=150/30=
