A
man went into his local bank to cash a check. In handing over the money,
the girl behind the counter mistakenly gave him dollars for cents and cents for
dollars. The man pocketed the money without even bothering to examine
it. On the way home, he spent a nickel. He then found that he
possessed exactly twice the amount for which his check had been made out.
If he had no money in his pocket before going to the bank, can you tell how much
his check was for?
