Answer: $3.60 will be spent on the necklace.
Step-by-step explanation:
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).
24 x 0.15= $3.60
S000, $3.60 will be spent on the necklace.
