Explanation:

1. For Nancy's calculation: Total cost is ticket cost plus parking cost, so both values are already identified as needed.
2. For Colby's calculation: To find used sugar, we need total delivered sugar (since Used = Total - Left; the listed "Sugar used per day" is incorrect here).
3. For Josephina's calculation: Total passengers = People per trip × Number of trips, so the missing value is total number of trips.
4. For the assembly line supervisor: Motorcycles per hour = Total motorcycles / Total time spent building, so the missing value is total time (hours) spent building.
5. For the animal control officer: To estimate total prairie dogs, we use a conversion factor between prairie dog holes and average number of prairie dogs per hole, so the missing value is average number of prairie dogs per hole.

Answer:

1. Nancy's calculation: The required information (cost of ticket, cost of parking) is already provided.
2. Colby's calculation: Total amount of sugar delivered (lbs)
3. Josephina's calculation: Total number of trips the bus makes
4. Assembly line supervisor calculation: Total time spent building motorcycles (hours)
5. Animal control officer calculation: Average number of prairie dogs per hole
