480.

There is 1 before 8. And 1 is below not 5 or more in order to round up to 490. So, the only choice is to stay at 480. Therefore, the answer is 480.

X would have to equal 10. This would be the answer because the numbers have to be proportional. To do that all you have to do is do 12/8. Then you get 1.5. Then you do the same for 15. Do 15/1.5 and get 10.
