To determine if Cindy has enough beads to make 15 complete rings, we start by calculating the total number of beads required for these rings.
-
Calculate the total beads needed for 15 rings:
- Each ring requires 60 beads.
- To find the total number of beads needed for 15 rings, we multiply the number of rings by the number of beads per ring:
\[ \text{Total beads needed} = \text{Number of rings} \times \text{Beads per ring} \]
\[ \text{Total beads needed} = 15 , \text{rings} \times 60 , \text{beads/ring} \]
\[ \text{Total beads needed} = 900 , \text{beads} \]
-
Determine if Cindy has enough beads:
- Cindy has 852 beads.
- We need to compare the total beads she has with the total beads needed:
\[ \text{Beads Cindy has} = 852 , \text{beads} \] \[ \text{Total beads needed} = 900 , \text{beads} \]
We can see that \(852 < 900\).
-
Conclusion:
- Since 852 beads are less than the 900 beads required for making 15 complete rings, Cindy does not have enough beads to make 15 complete rings.
Thus, Cindy will need to acquire more beads to complete her project for the craft show. Specifically, she needs:
\[ \text{Additional beads needed} = \text{Total beads needed} - \text{Beads Cindy has} \]
\[ \text{Additional beads needed} = 900 , \text{beads} - 852 , \text{beads} = 48 , \text{beads} \]
Cindy needs 48 more beads to make 15 complete rings.
