2015-06-06 Cap'n Crunch Gift Card Math

A question arose this morning while Nigel was looking at the back of a box of Cap'n Crunch: Which is more in total, 1,000 $50 gift cards or 500 $20 gift cards. Some discussion produced a specific answer for each, though it would also have been a good opportunity to discuss estimation techniques (e.g. multiplying a smaller number by another smaller number will never be larger than multiplying a larger number by another larger number).
