Chen Ding and Wei Zi.

Because the price of 1 eraser+1 ruler =3.68 yuan,

So the price of three erasers+the price of three rulers =3.68×3= 1 1.04 yuan,

And because the price of three erasers+the price of four rulers = 13. 14 yuan,

So the price of 1 ruler = 13. 14 yuan-1 1.04 yuan,

Price 1 ruler =2. 1 yuan,

Because the price of 1 eraser+1 ruler =3.68 yuan,

So the price of 1 eraser =3.68 yuan -2. 1 yuan.

Price 1 eraser = 1.58 yuan.

Answer: 1 eraser 1.58 yuan, 1 ruler 2. 1 yuan.
