Nerd time

My dad just yelled to me: "Hey, Robyn, I got a bookkeeping question for you.
"Two people, both aged 60, start saving money monthly, except the second one doesn't start saving until they are both 65. If the first person is saving $700 a month, and the second $100 a month, how long will it be after the second person starts saving for their accounts to be even (excluding interest, simple or otherwise)?"
I looked at my dad, then got up and asked him for a pen and paper. I clarified the problem, considered a tiny bit more and scribbled this down: 4200+700x=1000x then I looked at what I had written and corrected it to: 42000+700x=1000x and handed it to my dad while asking if that was what he had come up with. He said nothing, but asked me if I was sure. I talked through it with him and he was shocked to find out that x=140, or 11 years 8 months, when the two people are almost 77.
I then walked back here while yelling to my stepmom that: "He tricked me, telling me it was a bookkeeping question when it was an algebra word problem!"

Math is evil and devious. It stirs the mind to wicked thoughts, and as you can see only leads to deception!

Now, come on. Math is your frieeeeennnnnnd. Seriously, what's with people and math? Nothing is arbitrary and skay, like English. NOW ENGLISH, there's a sinister and deadly beast if I ever met one.
This may be the only thing we disagree on. Of course, the vast majority of Earth disagrees with me on this one.

skay=shaky...don't ask how, it just does

Yeah, that is kinda weird! I was an English Major, too. :P So we definitely disagree on this, on all points.
