Hi can someone help me with this problem?
A software programmer does 20% of the work in 80% of the time, and 80% of the work in the remaining 20% of the time. If the code he writes is X lines long and he was given one month(30 days) to accomplish the task, assuming that the programmer works at a constant rate in each of the two stages, how many lines of codes were written in the last two week, in terms of X?
A) 13x/15
B) 7x/15
C) 7x/60
D) 2x/3
E) x/2
