1379= 1380
38=40
1380 x 40 = 55,200
Or you can use the ≈ sign which means about so
1380 x 40 ≈ 55200
The first to solve x, because it eliminates y. Third one to solve y, because it eliminates x.

85% of 36000 is 30600
9% of 30600 is 2754
30600 - 2754 = 27846
I'm fairly sure that's right, but I wouldn't say no to a second opinion
