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

### Instruction:
Joel collected a bin of old toys to donate. By asking his friends, he was able to collect 18 stuffed animals, 42 action figures, 2 board games, and 13 puzzles. His sister gave him some of her old toys from her closet, and then Joel added twice as many toys from his own closet as his sister did from hers. In all, Joel was able to donate 108 toys. How many of the donated toys were Joel’s?

### Response:
 Acha T iwe idadi ya vitu ambavyo dada yake Joel alitoa.
Joel alitoa vitu mara mbili zaidi, kwa hivyo alitoa vitu 2T.
Marafiki wa Joel walitoa vitu 18 + 42 + 2 + 13 = 75.
Jumla, Joel alikusanya T + 2T + 75 = 3T + 75 = 108.
Joel na dada yake walichangia vitu 3T = 108 - 75 = 33.
Hivyo, T = 33 / 3 = <<33/3=11>>11 vitu vilikuwa vya dada yake.
Joel alitoa 2T = 2 * 11 vitu = <<2*11=22>>22 vitu.
Hivyo, kati ya vitu 108 alivyochangia Joel, vitu 22 vilikuwa vya Joel.
