Answer 9

yw :) notice that the number of chairs you can produce will reduce if any of the two variables are decreased - days / workers

Answer 10

which also makes sense intuitively -
if u have fewer days, u can produce fewer chairs only
if u have fewer workers, u can produce fewer chairs only

Answer 11

\(\large \text{# of chairs } \propto \text{ # of days}\)


\(\large \text{# of chairs } \propto \text{ # of workers}\)
