Question

If p is directly proportional to q and if p = 14 when q = 8, what is the value of p when q = 28?

Answer 1

Here is how we show a `direct` relationship:\[\Large\rm p=kq\]Where k is some constant of proportionality.
To find k, we use the information they gave us:\[\Large\rm p=14,\quad q=8\]
\[\Large\rm 14=8k\]So what do you get for your k value?
That will get us half way through this problem.
