Assume a demand equation:

$Q_d=9-0\mathrm{.}1p-p_b+0\mathrm{.}01p_{cm}+0\mathrm{.}0001Y$

and a supply equation:

$Q_S=0\mathrm{.}1p-0\mathrm{.}02p_{fg}+0\mathrm{.}01N+0\mathrm{.}01T-0\mathrm{.}1w$

where:

$\backslash$table$[[p=$ price of lobster,$Q=$ quantity in thousands of units$],[p_b=$ price of butter $=$$$3,p_{fg}=$ price of fishing gear $=$$$450$
