Contest Winner I Suppose you just won a contest and are given the choice of 2 prizes: $100,000 in cash right now or the final result of doubling $1.00 every day for a 3-week period. Which one would you choose? Show all work and use complete sentences to explain the benefits of one choice over the other. Hint: Constructing a table might help in organizing your information.

Learning Target L5 (Core): I can correctly structure a careful mathematical proof including all relevant English and mathematical statements. Please remember the academic integrity policy that you swore to uphold. Proofs can be challenging. Just try your best. If you don't get it this week, you have many more opportunities! 1. Prove that if n is an integer and n is a multiple of 2, then 4n+ 24 is a multiple of 8. 2. Show that if a = b (mod m) and b = c (mod m) where a and b are non-zero integers and m is a positive integer, then a = c (mod m). (Recommended start: write the congruences as statements of divisibility, and divisility as equalities, then go from there). You can use our text, videos, notes etc, posted to Discourse. No other outside resources (including humans) are allowed.
