Answer:
528 dollars
Explanation:
The starting price is $600. And it goes down by 20% then comes back up 10% so steps are:
First we got 20% off so I did 100 - 20 and got 80%
1: 80% * 600 = 80/100 * 600 = 480
Then we get an increase of 10% so I multiplied 110% with 480 which was our new price
2. 110/100 * 480 = 11 * 48(simplifying)
= 528
