Briley Cosmetics manufactures and distributes a wide range of skin care products. A recent order has arrived for 10,000 cartons of face cream, 5,000 cases of body cream, and 15,000 cases of hand cream.

A second shift is available with a 10% reduction in capacity and a 10% increase in wage rates. The cost for raw materials is $1/pound for Type A and $1.50/pound for Type B.
