Your answer is 234 because the grid goes by 100 and if the grid is fully shaded it means that it is 100. So you take the two fully shaded grids and make them 200. Next you add the 3 of the ten columns and that makes 30 and take the 4 shaded squares and combine the two. Finally add them all together and get 234. Step by step equations down below.

Equations:

100+100=200
30+4=34
200+34=234
