Puzzle
- US Version
"I bought this beautiful, one-of-a-kind fountain pen from a luxury boutique for 10% off the original price of only $3,000!
When I showed it to my friend, she took one look and just had to have it! She offered to pay be 10% more than what I'd paid. I love the pen, but I couldn't say no!
Overall, how much did I gain or love by selling the pen to my friend?"
Be sure to put a minus sign (-) in front of your answer in case of a loss.

Overall, how much did I gain or lose?"

Think about it carefully.

You got it!
She will make a profit of $270.
The pen was originally bought for 10% off of $3,000. Which is $2,700, and sold for 10% more than $2,700, which is $2,970. This makes for a profit of $2,970 minus $2,700, which is $270!
- UK Version
Correct!
"It was a £2.70 gain.
The initial 10% discount I got in the shop determines the price I had to pay for the pen (£30.00 - £3.00 = £27.00), but it doesn't affect the 10% gain I made later when I sold it on to my friend.
I bought the pen for £27.00 and sold it for 10% more (£27.00 + £2.70 = £29.70), making a profit of £2.70, or 270 pence."
