Final answer:
The maximum amount of marijuana under 1 oz is a little less than 28.349 grams, which is the conversion for 1 oz. Therefore, the closest correct answer from the options given would be 28.5 grams, even though it's slightly over, since no exact number just under 28.349 grams is provided.
Step-by-step explanation:
The question asks about the maximum amount of marijuana considered under 1 oz. Using the conversion factor from the given information, we know that 1 oz equals 28.349 grams. To find the maximum amount under 1 oz, we look at the options provided and identify which one is the largest number less than 28.349 grams.
The options are:
- 28.5 grams
- 30 grams
- 25 grams
- 35 grams
Options 2 and 4 are clearly above 28.349 grams, so they are not correct. Between options 1 and 3, 25 grams is less than 28.349 grams, but since we are looking for the maximum amount "under 1 oz," the best choice would be just under 28.349 grams. Therefore, the correct answer is 28 grams, which is not explicitly listed but would be understood as slightly less than the conversion value of 28.349 grams making option 1 the closest one.
