Product Mix Problem TJ's Inc., makes three nut mixes for sale to grocery chains located in the southeast.

Product Mix Problem

TJ’s Inc., makes three nut mixes for sale to grocery chains located in the southeast. The three mixes, referred to as the Regular Mix, the Deluxe Mix, and the Holiday Mix, are made by mixing different percentages of types of nuts.

In preparation for the fall season, TJ’s has just purchased the following shipments of nuts at the prices shown:

Type of Nut

Shipment Amount (pounds)

Cost per Shipment
















The Regular Mix consists of 15% almonds, 25% Brazil nuts, 25% filberts, 10 % pecans, and 25% walnuts. The Deluxe Mix consists of 20% of each type of nut and the Holiday Mix consists of 25% almonds, 15% filberts, 25% pecans, and 20% walnuts.

TJ’s accountant has analyzed the cost of packaging contribution per pound, and so forth, and has determined that the profit contribution per pound is $1.65 for the Regular Mix, $2.00 for the Deluxe Mix, and $2.25 for the Holiday Mix. These figures do not include the cost of specific types of nuts in the different mixes because that cost can vary greatly in the commodity markets.

Customers orders already received are summarized below:

Orders (pounds)







Because demand is running high, it is expected that TJ’s will receive many more orders than can be satisfied.

TJ’s is committed to using the available nuts to maximize profit over the fall season; nuts not used will be given to the Free Store. But even if it is not profitable to do so, TJ’s president has indicated that the orders already received must be satisfied.
