Final answer:
Emery invited a number of friends to her birthday party that is a multiple of 3. The possible answers from the given options are 9 (option A) or 15 (option C), as both of these are multiples of 3.
Step-by-step explanation:
The student has asked how many friends Emery invited to her birthday party which is a multiple of 3. To solve this, we look at the options provided:
- A. 9 Friends
- B. 16 Friends
- C. 15 Friends
- D. 8 Friends
We know that a multiple of 3 is a number that can be divided by 3 without leaving any remainder. Now, analyzing the options:
- 9 is 3 times 3, so it is a multiple of 3
- 16 is not divisible by 3 without a remainder
- 15 is 5 times 3, so it is a multiple of 3
- 8 is not divisible by 3 without a remainder
Therefore, the numbers that are multiples of 3 from the choices are 9 and 15. If the question allows for more than one answer, both A (9 friends) and C (15 friends) would be correct. However, if only one answer is allowed, we would need additional information to determine which one is correct. Since that information is not provided, we consider all multiples of 3 to be correct answers.
