Description : What do you think of this approach to solving mixture algebra problems?
Last Answer : Perhaps I should have introduced weighted averages with GPAs, which most people are familiar with. We have w1 s1 + w2 s2 + ... + wn sn = s, where the wi weights of tests are determined in advance and the si ... for x in w1 s1 + w2 s2 + ... + wn x = s. This is a fairly straightforward calculation.
