Earrings = 10
Bracelets = 15
Necklaces = 25

Earrings = Bracelets + 10
Necklaces = Bracelets - 2

If she sold 18 Necklaces:

-----------------------------
Necklaces = Bracelets - 2

18 = Bracelets - 2

Bracelets = 20
-----------------------------
Earrings = Bracelets + 10

Earrings = 20 + 10

Earrings = 30
-----------------------------

Bracelets = 20
Earrings = 30
Necklaces = 18

20(15) + 30(10) + 18(25)

300 + 300 + 450

1050

So she sold 18 Bracelets, because her total was $1,050 and that's what we got.
