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

### Instruction:
Olga has three stripes on the side of each of her tennis shoes.  Rick has one less stripe per shoe than does Olga.  But Hortense has double the number of stripes on her tennis shoes as does Olga.  In total, what is the combined number of stripes on all of their pairs of tennis shoes?

### Response:
 Rick ana milia moja chini ya tatu, au 3-1=2 milia kwenye kila kiatu cha tenisi.
Hortense ana mara mbili ya milia 3 ambayo Olga ana, au jumla ya milia 2*3=6 kwenye kila kiatu cha tenisi.
Kwa kuwa kila mmoja wao ana viatu vya tenisi 2 kwa kila jozi, basi jumla ya milia kwenye viatu vyao vyote ni 2*(3+2+6)=22 milia.
