To determine if Cindy has enough beads to make 15 complete rings, we need to calculate the total number of beads required for all the rings and then compare that to the number of beads she has.
-
Calculate the number of beads needed for one ring:
- Each ring requires 60 beads.
-
Calculate the total number of beads needed for 15 rings: \[ \text{Total beads needed} = \text{Number of rings} \times \text{Beads per ring} \] \[ \text{Total beads needed} = 15 \text{ rings} \times 60 \text{ beads/ring} \] \[ \text{Total beads needed} = 900 \text{ beads} \]
-
Compare the total beads needed with the number of beads Cindy has:
- Cindy has 852 beads.
-
Determine if she has enough beads:
- We need to check if 852 beads are greater than or equal to 900 beads. \[ 852 < 900 \]
Conclusion
Cindy does not have enough beads to make 15 complete rings. She needs 900 beads but only has 852 beads. Therefore, she is short by: \[ 900 - 852 = 48 \text{ beads} \]
So, Cindy needs an additional 48 beads to complete all 15 rings.
