Math Fun Day #1 - Pennies, a Princess, Pirates and Soda
Yesterday we had our first #mathfunday through google hangouts, and it was awesome! @sweenwsweens, @j_lanier, @wahedabug, @JustinAion and @occam98 got together and solved 3 interesting problems, discussed teaching methods, came up with extensions and of course joked around a bunch. Join us for our next math fun day Thursday, May 30th at 9 PM EST. Come with a compelling problem to share if you can find one.
Math Fun Day 1 Problem #1: A Penny a day...
Problem #1: You get one penny per day for life. After how many years will your money have the most value, considering inflation is roughly 2.5%?
Bonus: If you saved the pennies up for 100 years what would the value of your money be?
Pretty sad right? Enjoy your lunch. Pennies are pretty much the worst.
