Using proportions, it is found that due to the smaller cost per bead, the large pack is the better value.
The pack with the better value is the one with the lowest cost per bead.
The small pack, with 90 beads, costs $3.60, hence, the cost per bead is:
[tex]C_s = \frac{3.6}{90} = 0.04[/tex]
The large pack, with 300 beads, costs $9.00, hence, the cost per bead is:
[tex]C_l = \frac{9}{300} = 0.03[/tex]
Due to the smaller cost per bead, the large pack is the better value.
