Barbara wants to buy some glittery heart-shaped beads to make friendship bracelets. The beads she wants come in a small pack with 90 beads or a large pack with 300 beads. The small pack costs $3.60, while the large pack costs $9.00. Which pack is the better value?

Answer 1

To determine which pack of beads is the better value, we can calculate the cost per bead for each pack.

1. Small Pack:

   • Cost: $3.60
   • Number of beads: 90
   • Cost per bead: \( \text{Cost per bead} = \frac{\text{Total Cost}}{\text{Number of Beads}} = \frac{3.60}{90} = 0.04 \) (or 4 cents per bead)

2. Large Pack:

   • Cost: $9.00
   • Number of beads: 300
   • Cost per bead: \( \text{Cost per bead} = \frac{9.00}{300} = 0.03 \) (or 3 cents per bead)

Comparing the two:

• Small pack: 4 cents per bead
• Large pack: 3 cents per bead

The large pack is the better value, as it costs 3 cents per bead compared to 4 cents per bead for the small pack.
