Answer:
$66
Step-by-step explanation:
from the question,
let cost for one purse = X
let cost for one necklace = Y
from the question,
2Y+ 3X= 208.50-------(1)
Y + X = 91.50----------(2)×3
3Y + 3X =274.5--------(3)
subtract equation equation 2 from 3
3Y + 3X = 274.50
2Y + 3X =208.50
Y = 66
cost of one necklace= $66
