If 42.12 = k(14 + m/50), where k and m are positive integers and m < 50, then what is the value of k + m ?  Choices.
A) 5 B) 7 C) 8 D) 9 E) 10
42.12 = 14K + Km/50...we can rewrite the number as follows:   42+ 0.12= 14K + Km/50........Since K is integer, then 42=14K..........K=3   0.12=Km/50......12/100=3m/50......m=2   k+m=3+2=
