Answer: Lost $500

Vanessa Petty · Answer 2

By buying the necklace, she lost $300.

This means she has - 300 dollars.

Then, she gained $600 for selling the necklace. Add 600.

-300 + 600 = 300

She now has $300 again.

Next, she buys it for $700. Subtract 700.

300 - 700 = - 400

She has negative $400.

Finally, she sells it for $900. Add 900.

-400 + 900 = 500

She has $500 at the end.

Answer:

She gained $500 from the transactions.
