751,447 rounds to 800,000, because it has if you have 5 or over you round up. As for 817,245 it rounds to 800,000, because if you have 4 or less then you round down.
If you want to solve 
for 
, start by getting rid of the fraction.
Multiply both sides of the equation by .
This will get rid of the fraction on the left and give you
Now this is a regular old equation without fractions. To get by itself, you need to divide away 
from both sides of the equation.
Can you finish it from there?
Answer:
528 dollars
Step-by-step 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
