Answer:
The correct answer is 7.
Explanation:
The first thing we should do is analyze the information we have.
We know that Janell uses 66 beads for each necklace she makes. And if she bought 500 beads, what corresponds is that we divide the total beads by the one she uses for each necklace.
500: 66 = 7.57 ...
As we can see, we have not obtained an integer, which indicates that Janell will have 57 beads left over, which are not enough to make another necklace, since she uses 66. Therefore, she can only make 7 necklaces.
