The Whitewave dairy company produces three cheese spreads- Regular, Zesty and Superior. The cheese spreads are packaged in 4 pound containers, which are then sold to distributors throughout the Northeast. The Regular blend must have at least 5% extra sharp cheddar, the Zesty blend must contain at least 24% extra sharp cheddar and the Superior blend must contain at least 30% extra sharp cheddar. The company has orders for 3500 containers of Regular, 4500 containers of Zesty and 1000 containers of Superior.

They can offer up to 7600 pounds of ingredient 1 for $1.15 per pound and up to 8900 pounds of ingredient 2 for $1.55 per pound. Ingredient 1 consists of 85% mild cheddar and 15% extra sharp while ingredient 2 consists of 45% mild and 55% extra sharp.
