Answer:
A soultion is provided that makes assumptions about missing information.
Explanation:
The statement ". . . each goose gets 16 oz . . ." is missing some information about a time frame. Is it 16 oz per day, week, month? The question cannot be answered without this information.
We also don't know the relationship between the number of seeds and ounces. Is 16 oz 1 seed, 10 seeds, 1000 seeds? Again, we cannot solve this without additional information.
To add some insight how to solve the problem, lets make two assumptions:
Assume 16 oz/week. We can write this as a conversion factor: (16 oz food)/(1 snow goose).
Assume 10 seeds/oz.
The Rescue Center has 1,656 seeds in total.
(1,656 seeds)
Each snow goose gets 16 oz of seeds a week. That is (16 oz)*(10 seeds/oz) = 160 seeds/week per goose.
There are 9 geese, so they consume (9 geese)*(160 seeds/week/goose) = 1440 seeds/week
There are 1,656 seeds. At 1,440 seeds/week, they will last (1,656 seeds)/(1,440 seeds/week) = 1.15 weeks.
