Teresita wanted to buy a dress for $50, but she decided to wait because she didn't have enough money. A week later, the price had gone up 20%. Now she definitely had to wait to
buy it. A week later, she went back to the store, and the price had gone down 20% from the
last price. Teresita finally bought the dress. What did she pay for it?

$48

Explanation:

> 50 x .20 = $10

$50 + $10= $60
