The Fido Dog Food Company wishes to introduce a new brand of dog biscuits (composed of chicken and liver-flavored biscuits) that meets certain nutritional requirements. The liver-flavored biscuits contain 1 unit of nutrient A and 4 units of nutrient B, while the chicken-flavored ones contain 2 unit of nutrient A and 2 units of nutrient B. According to federal requirements, there must be at least 40 units of nutrient A and 60 units of nutrient B in a package of...

Kimon’s dog, Bobos, every day eats on average 3 pounds of kibble with a standard deviation of 0.5 pounds. Kimon buys the kibble from an online retailer that charges $2 per pound of kibble. The retailer guarantees a 2-day delivery and the delivery fee is equal to $20. Living in a small house Kimon doesn’t have too much storage space, so he estimates that keeping a pound of kibble in the cabinet essentially costs him $0.2 per week. The retailer...
