If 42.30 = k(14 + m/50), where k and m are positive integers and m < 50, then what is the value of k + m ? Choose the most appropriate option:  A) 6  B) 7  C) 8  D) 9  E) 10
42.30 = 14K + Km/50...we can rewrite the number as follows:   42+ 0.30= 14K + Km/50........Since K is integer, then 42=14K..........K=3   0.30=Km/50......40/100=3m/50......m=5   k+m=3+5=
