But instead make pesin go through all dat stress, Tom Sawyer don trade different toys and treasures with him friends until he gather 8 yellow, 3 red, and 7 blue tickets. How many more blue tickets e go need to earn to win new Bible?" <response>: ```
One red ticket na equal to 10 blue tickets, and one yellow ticket na equal to ten red tickets, so one yellow ticket na also equal to 10 * 10 = 100 blue tickets.
E go need 10 yellow tickets to win Bible, wey be 10 * 100 = 1000 blue tickets.
Tom get 8 yellow tickets, wey worth 8 * 100 = 800 blue tickets.
E still get 3 red tickets, wey worth 3 * 10 = 30 blue tickets.
Plus hin 7 blue tickets, e get 800 + 30 + 7 = 837 blue tickets worth of tickets.
So e still need to earn 1000 - 837 = 163 blue tickets.

Answer na 163.
