Infinity squared is infinity, so it follows that the square root of infinity is also infinity. Probably.
These questions are much harder than each other.
2) If Kyle put the whole of it into the 3% account, then she would get 20,000x3%=$600.
For however much she puts into the 5% account, she gets 5-3=2% more.
She got $760 and she gets $600 from the low rate, so she needs $160 more.
If it was all in the high rate account, she would get 20,000x2%=$400 more, but she only wants $160. (Don't know why, though)
This means that she puts 160/400=40% of her money, or $8,000, in the high account.
To summarise, $8,000 at 5% and $12,000 at 3%.
Sorry if I've just made this more complicated with my bad explanation.

I've been here for a while now, but I've just registered so I thought I'd post here.
OK, done that. Bye!
