A store sells two types of toys, A and B. The
store owner pays $8 and $14 for each one unit
of toy A and B respectively. One unit of toys A
yields a profit of $2 while a unit of toys B yields
a profit of $3. The store owner estimates that no
more than 2000 toys will be sold every month
and he does not plan to invest more than
$20,000 in inventory of these toys. How many
units of each type of toys should be stocked in
order to maximize his profit?
