Hi, do you have the answer key for this question? I’m interested in knowing how to arrive at the final answer for this question as well. I’m not sure if I understood the question correctly, but based on my interpretation of the question, I believe that it can’t be solved (I end up constructing 2 simultaneous equations with 3 unknowns which means I’m unable to solve for all the unknowns).

Do let me know if you have the answer! Thanks!
