Answer 2

Answer: $3.60 will be spent on the necklace.

Step-by-step 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).

• 24 x 0.15=  $3.60

In conclusion, $3.60 will be spent on the necklace.
