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

### Instruction:
Max likes to collect model trains.  He asks for one for every birthday of his, and asks for two each Christmas.  Max always gets the gifts he asks for, and asks for these same gifts every year for 5 years.  At the end of the 5 years, his parents give him double the number of trains he already has.  How many trains does Max have now?

### Response:
 Max anapata 1+2=<<1+2=3>>3 treni kwa mwaka.
Anarudia hii kwa miaka 5, maana yake anapata 5*3=<<5*3=15>>15 treni.
Kabla wazazi wake hawampi zaidi, ana treni 15.
Wazazi wake wanachagua kumpa mara mbili idadi hii, hivyo wanampa 2*15=<<2*15=30>>30 treni.
Sasa jumla, Max ana treni 30+15=<<30+15=45>>45.
