Kayla uses fancy beads which she purchases online to make bangle bracelets. The chart shows the number of different designer beads in one bag, and only full bags are sold. If Kayla chooses the BEST DEAL, how much will 1200 beads cost?
Responses
A $48.00$48.00
B $56.00$56.00
C $65.00$65.00
D $70.00
To find the best deal, we need to calculate the cost per bead for each option:
Option A:
- 25 beads in a bag for $1.50
- Cost per bead = $1.50 / 25 = $0.06
Option B:
- 30 beads in a bag for $2.00
- Cost per bead = $2.00 / 30 = $0.0667
Option C:
- 35 beads in a bag for $2.30
- Cost per bead = $2.30 / 35 = $0.0657
Option D:
- 40 beads in a bag for $2.50
- Cost per bead = $2.50 / 40 = $0.0625
Option D has the lowest cost per bead, so it is the best deal. To find out how much 1200 beads will cost at this rate:
1200 beads * $0.0625 = $75.00
Therefore, the cost of 1200 beads at the best deal rate is $75.00, which is not one of the options listed.
