Pressure Cooker for Profit

A friend of mine bought a used pressure cooker for $60. She somehow did not find it useful and so when a friend of hers offered her $70, she sold it to her. However, she felt bad after selling it and decided to buy it back from her friend by offering her $80. After having bought it once again, she felt that she did not really need the cooker. So she sold it at the auction for $90.

How much profit did she make? Did she at all make any profit?
