tmara is making a medium length necklace. write an expression that shows how nuch it will cost tamara for the chain, pendant, and b beads that cost $0.25 each. Then find the total cost of the necklace if tamara uses 30 beads.

1/4(n), $7.50

Step-by-step explanation:

Expanded: cost = 0.25 * chains + 0.25 * pendants + 0.25 * beads

Simplified: c = (1/4)(total number of items)

Expression only: 1/4n where n = # chains + # pendants + # beads purchased

Total cost of 30 beads = 1/4(30) = 7.5 = $7.50

sin3a=12/15
