Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
There are 20 students in the orchestra and twice that number in the band. There are 12 boys and 16 girls in the choir. If each student only participates in one group, how many students, in total, are there in the orchestra, the band, and the choir?

### Response:
 Idadi ya wanafunzi katika bendi ni 20 * 2 = <<20*2=40>>40.
Jumla ya wanafunzi katika kwaya na kikundi cha muziki wa filimbi ni 12 + 40 + 20 = <<12+40+20=72>>72.
Kuongeza idadi ya wasichana katika kwaya kunafanya jumla kuwa 72 + 16 = <<72+16=88>>88 wanafunzi.
