Question

The amount of time needed to stuff And address envelopes for the local high school fundraising campaign Varies inversely with the number of parent and student volunteers that attend the envelope stuffing event last year took 20 people 3 hours to stuff in the dress the envelopes. how many people are needed to stuff in the dress all of the envelopes

Answer 1

The time (t) needed to stuff and address envelopes varies inversely with the number of people (p);

$\begin{gathered} t\text{ }\alpha\text{ }\frac{1}{p} \\ t=\frac{k}{p} \\ k=pt \\ k=20\times3 \\ k=60 \end{gathered}$

This means it will take one person 60 hours to get the envelopes addressed and stuffed.

However, from the question, we were already told the number of people needed to stuff and address all of the envelopes. It took 20 people to stuff all the envelopes a year before. It is just a common reasoning question that does not require any calculation. The answer has already been stated for us in the question.

Therefore, over the same period of time, it will take 20people as well to stuff and address the envelopes.
