2x + 115,000 = 505280
2x = 390,780
x = 195,390

America = x + 115,000 = 310,390
China = x = 195,390

Just to check, 310,390 + 195,390 = 505,780.

Let the number in China be x.

USA has 115 000 more than China  =  x + 115000

Total = 505 780

x + (x + 115000) = 505780

x + x + 115000 = 505780

2x + 115000 = 505780

2x = 505780 - 115000

2x = 390780

x = 390780/2

x = 195 390

So China is x , 195 390,  USA = x + 115000 = 195390 + 115000 = 310390 

China = 195 390

 USA = 310 390

Hope this clarifies it.

This brings you to the answer of 1.2D
