How do you capture observations in your day-to-day life? Think about the notes you take in your everyday world. Maybe you have a day planner where you keep information about your schedule, who you meet with and what you discuss, your “to do” list, or chores other family members or friends help with. How do you maintain that information so it’s usable? How do you organize it so you can look back and know all of the information you need to stay on top of?

Oz makes lion food out of giraffe and gazelle meat. giraffe meat has 18 grams of protein and 36 grams of fat per pound, while gazelle meat has 36 grams of protein and 18 grams of fat per pound. a batch of lion food must contain at least "46,800" grams of protein and 70,200 grams of fat. giraffe meat costs $1/pound and gazelle meat costs $2/pound. how many pounds of each should go into each batch of lion food in order to minimize costs? hint [see example 2.]
