- A kennel raises Doberman pinschers and German shepherds. The
kennel can raise no more than 40 dogs and wishes to have no more than
24 Doberman pinschers. The cost of raising a Doberman pinscher is
$50, the cost of raising a German shepherd is $30, and the kennel
can invest no more than $1500 for this purpose. Find a system of
inequalities which describes the number of Doberman pinschers and
German shepherds that can be raised by the kennel.
