Q$1.$ Use Figure $7\mathrm{.}4($p$.235)$ to check that combinations of B and D inside the capital constraint

line are feasible, but use up fewer than the $100$ units of capital available $($e$.$g$.$ check

$B=10,D=5).$

Use Figure $7\mathrm{.}4$ to check that combinations of B and D outside the capital constraint

line are not feasible, but use up more than the $100$ units of capital available $($e$.$g$.$ check

$B=20,D=10).$Neume $7\mathrm{.}4$ Graphing the contrainta as equalition
