Answer: $3.60 will be spent on the necklace.
Explanation:
Hi, to solve this problem we have to divide the length of the necklace (30cm ) by the diameter of each bead (1.25) to obtain the number of beads needed for the necklace.
So, mathematically speaking:
- 30 cm / 1.25 cm =24 beads
Now, we have to multiply the number of beads by the cost of each one ($0.15).
In conclusion, $3.60 will be spent on the necklace.
