Question

The amount of time needed to Stuff and address envelopes for the local high schools followers in campaign varies inversely with the number of parent and student volunteers that attend the envelope stuffing event last year It took 20 people 3 hours to stuff in the dress the envelopes select the equation that could be used to estimate the amount of time Y, it will take the X number of volunteers to stuff and address the same number of envelopes.

Answer 1

This is a proportion question. In this case, it states that the time, y, and the number of volunteers, x, are inversely proportion. So:

20 -- 3

x -- y

Because the proportion is inverse, we inverse one of them to write the equation:

$\begin{gathered} \frac{20}{x}=\frac{y}{3} \\ y=\frac{60}{x} \end{gathered}$

The equation asked is:

$y=\frac{60}{x}$
