### Instruction:
The kindergartners each need to bring one mini tissue box to class for the school year.  There are three kindergartner groups with 9, 10, and 11 students respectively.  Each mini tissue box contains 40 tissues.  How many tissues do the kindergartner groups bring together?

### Response:
The kindergartner groups bring together 9+10+11=<<9+10+11=30>>30 mini tissue boxes
Each box contains 40 tissues, so 30*40=<<30*40=1200>>1200 tissues
#### 1200
