The table below gives the number of Jerry's Construction workers needed to frame a specific type of house in certain selected numbers of days. Given that all the workers work at the same rate, how many workers will it take to frame this specific type of house in 10 days?

$$ \begin{array}{|c|c|} \hline \text{Workers} & \text{Days} \\ \hline 2 & 15 \\ ? & 10 \\ 6 & 5 \\ 30 & 1\\ \hline \end{array} $$

If it takes 6 workers 5 days, then having half the number of workers will result in it taking twice as long.

The number of workers and days are indirectly related.

$$ wd = k $$

We can use any entry to obtain the constant of proportionality.

$$ (2)(15) = k $$ $$ k = 30 $$ $$ wd=30 $$

Plugging in 10 days,

$$ w(10)=30 $$ $$ w= \boxed{3} $$
