Re: Math in careers
Thanks for reviving this thread just in time. I have to give a talk in 2 days to 8th graders on why they should care about math and what careers use it.
Anyone who uses a credit card should know how to use math or risk getting rooked. How much does an iPhone cost (not counting monthly fee)?
Cost if paid up front: $199
Cost if paid by credit card, minimum payment: $1192.24
--amortization calculation, principal = $199, minimum monthly payment of $3.97, 23.9% interest (the rate on some store credit cards), 25 years to pay off.
Kind of like the lotto, but probably even more people do it.
