Question

Lily paid $208.50 for 2 identical necklaces and 3 purses. Serena paid $91.50 for 1 such necklace and 1 purse. Each purse cost the same. How much did a necklace cost?

P.S. No algebra please! I have not learnt it yet!! Just simple equation will do. ; D​

Answer 1

$66

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
