@QuantReasoning your methodology is really practical, many kudos!! in 2:41 after factoring out 336 the terms are the estimated and actual time of E,B accordingly. Is it a coincidence or can we justify from this why we choose B?(for example because the actual time was different and it caused the reduction of the hourly rate we choose B whose actual time is the one term of the factored 336)
I'm not sure I follow your question, but please note that all four factors (12, 14, 24, and 28) appear in the answer choices. So we do have to apply some reasoning and be very careful with what exactly the question is asking for. It's asking for the estimated number of hours.
@QuantReasoning I know that all factors are in the choices, I just considered that maybe in the specific factoring of 336 (in 2:41) the 2 numbers which are the estimated of A,E and the actual of B, is some kind of hint. But apparently it is pure coincidence.
what an insane question
i like this explanation.
