### Instruction:
A bag of jellybeans contains 8 black beans and 2 more green beans. It also contains 1 less orange bean than green beans. How many jellybeans are there in the bag?

### Response:
 Idadi ya maharage ya kijani ni 8 + 2 = <<8+2=10>>10.
Idadi ya maharage ya machungwa ni 10 - 1 = <<10-1=9>>9.
Jumla ya maharage ni 8 meusi + 10 ya kijani + 9 ya machungwa = <<8+10+9=27>>27 maharage.
