I will do the first problem and not the second problem. The first problem is interesting but something seems wrong with it. The second problem is a Travel rate,time,distance kind and belongs in a different request.

Let p = how much vocabulary before the increase produced by foreign language classes. Taking foreign languages produced 1.6%2Ap, the count of vocabulary. The typical student who took no foreign language knew 1.6p-3250 words. If you expect a clear value, then the problem description is deficient.
