Four workers could do k jobs in m hours. At the same overall rate, how long would it take them to do 35 jobs?

Was looking at the wrong problem so I mixed them, get rid of the overall average rate part and replace it with, 'if three more workers were hired'.

First we substitute 4 for w, k for j, and m for t. Then we solve for r.

We get k over 4m for r. Then we do the equation rwt=j again, thus time substituting k over 4m for r, 35 for j, and 7 for w, then solve for t.

We get 20m over k hrs. Aren't abstract rate problems fun?
