5. Now we have two simple equations:
1) 100%=719.99
2) x%=549.99
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=719.99/549.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 549.99 is what percent of 719.99
