Brianna buys a bag of 256 beads. She gives away 96 of the beads and uses the beads she has left to make necklaces. Which graph shows the possible numbers of necklaces Brianna can make if she uses 8 beads for each necklace?
Let's solve this math problem step by step.
First, we need to find out how many beads Brianna has left after giving away 96 beads. We can do this by subtracting 96 from 256: 256 - 96 = 160.
Then, we need to determine how many necklaces Brianna can make with the remaining beads. Since she is using 8 beads for each necklace, we can divide the number of remaining beads by 8: 160 / 8 = 20.
Therefore, Brianna can make a maximum of 20 necklaces with the remaining beads.
Now let's look at the graph options:
A) [include graph A if it shows numbers less than 20]
B) [include graph B if it shows numbers greater than 20]
C) [include graph C if it shows numbers equal to 20]
Based on our calculations, the correct graph would be: C) [graph C shows the number 20].
To find the possible numbers of necklaces Brianna can make, we need to calculate the number of beads she has left after giving away 96 beads.
The number of beads she has left can be found by subtracting the beads she gave away from the total number of beads:
256 beads - 96 beads = 160 beads
Now, we can find the possible numbers of necklaces she can make by dividing the number of beads left by the number of beads needed for each necklace:
160 beads / 8 beads = 20 necklaces
Therefore, Brianna can make 20 necklaces using the remaining beads.
As for the graph, it would show the possible numbers of necklaces on the y-axis and the number of beads left after giving away 96 beads on the x-axis. The graph would have a single bar at the height of 20, indicating that Brianna can make 20 necklaces.
