After being asked this question at work [and knowing the best answer, of course], my husband came home to ask it of the kids.
If I hired you to work for 30 days, would you rather have $10,000 dollars a day or starting at 1 cent, earn double everyday for 30 days. I admit, I've known my husband long enough to know the right answer wasn't the obvious one. He didn't like calling it a "trick" question. Afterall it's not a trick, just math, but the kids all answered with a resounding...give me 10k a day!!
Go ahead...do the Math. [I'll wait...] Did it look something like this? [only without the cutest little girl in the world?] [and yes, my husband came on and made this Excelsheet for me!]
