Name withheld to protect ... well, me, actually. I don't want to be fired or, worse, given the third-year freshmen pre-algebra class.
Anyway, the problem posed in the previous picture had an incorrect solution. Mike inadvertantly used phi instead of phi % when solving his imaginary interest inquiry.
The actual result was a loss of about 1% of 1% of your original principal, which is better than many mutual funds performed in the past year. However, you would have picked up only an imaginary nickel, rather than a few imaginary dollars.
Special thanks to "anonymous" for running the numbers. I don't have the budget for a staff of fact checkers around here. And, oddly enough, although I managed to get the correct solution out of wolframalpha after the mistake was first pointed out to me, it took about five tries to get the equation entered correctly when I wanted to write this entry. Too many divisions and parentheses!
Oh, and ....
I meant to do that.
Yeah, that's the ticket.
