By definition we have to:

So:

Thus, we have to:

So, the value is -169

Option A
Answer:
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
