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

### Instruction:
To win a brand new Bible at Tom Sawyer's Sunday school, a pupil has to win 10 yellow tickets; each yellow ticket is obtained by trading in 10 red tickets; each red ticket is obtained by trading in 10 blue tickets; and blue tickets are earned by memorizing two Bible verses. But rather than go to all that trouble, Tom Sawyer has traded various toys and treasures of his with his friends until he has gathered 8 yellow, 3 red, and 7 blue tickets. How many more blue tickets would he need to earn to win a new Bible?

### Response:
 Tiketi nyekundu ni sawa na tiketi 10 za bluu, na tiketi ya manjano ni sawa na tiketi 10 za nyekundu, hivyo tiketi ya manjano pia ni sawa na 10 * 10 = <<10*10=100>>100 tiketi za bluu.
Inachukua tiketi 10 za manjano kushinda Biblia, au 10 * 100 = <<10*100=1000>>1000 tiketi za bluu.
Tom ana tiketi 8 za manjano, ambazo ni sawa na 8 * 100 = <<8*100=800>>800 tiketi za bluu.
Ana pia tiketi 3 za nyekundu, ambazo ni sawa na 3 * 10 = <<3*10=30>>30 tiketi za bluu.
Zikiwa pamoja na tiketi zake 7 za bluu, ana tiketi zenye thamani ya 800 + 30 + 7 = <<800+30+7=837>>837 tiketi za bluu.
Hivyo bado anahitaji kupata tiketi 1000 - 837 = <<1000-837=163>>163 za bluu.
