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
