Question 1016612
Let {{{ b }}} = number of boy bears that can be made
Let {{{ g }}} = number of girl bears that can be made
---------------------
(1) {{{ g <= 30 }}}
You can't have more girl bears than dresses for them
-----------------------
{{{ b + g <= 100/2 }}}
(2) {{{ b + g <= 50 }}}
Total number of  bears can't be more than the 
pairs of eyes
-----------------------
(3) {{{ b + g <= 60 }}}
Total number of  bears can't be more than the 
number of bows
-----------------------
(2) is the tighter restriction, so it rules
Also, I can subtract (1) from (2)
(2) {{{ b + g <= 50 }}}
--------------------
From (1) and (2),
{{{ b <= 20 }}}
