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...
