1. The problem statement, all variables and given/known data

This is a pigeonhole question, not an induction question.
hint:

If you have 10 different numbers, how many different ways can you choose a subset of them? (to make a sum)

and also,

what is the range of answers you can possibly get? (numbers chosen from 1-99 and up to a maximum of 10 numbers)
