We need to find out the value of equation

f + 9m

1. f + m = 0.9

we cannnot determine the value of 2 variables from 1 equation. hence insuff.

2. f+3m = 1.2

Again we cannot determine the value

1+2 , we have 2 variables and 2 equations, so we can find out the value of f and m and on subsituting the value in f+9m we can determine the cost of trip

hence C.
