Problem 3. Tom's Inc. makes two salsa products: Western Foods salsa and Mexico City salsa.
Essentially, the two products have different blends of whole tomatoes, tomato sauce, and tomato
paste. A jar of Western Foods salsa uses 5 ounce of whole tomatoes, 3 ounces of tomato sauce,
and 2 ounces of tomato paste. A jar of Mexico City salsa consists of 7 ounces of whole tomatoes,
1 ounce of tomato sauce, and 2 ounces of tomato paste.
For the current production period Tom's Inc. can purchase up to 4480 ounces of whole tomatoes,
2080 ounces of tomato sauce, and 1600 ounces of tomato paste. Tom's Inc. makes a profit of
$1.00 per jar of Western Foods salsa and $1.25 per jar of Mexico City salsa. The following linear
optimization model was used to determine the mix of salsa products that will maximize the total
profit contribution.
