Modern Puzzles by Henry Ernest Dudeney: $3$

Dollars and Cents

An American correspondent tells me that a man went into a store and spent one-half of the money that was in his pocket.

When he came out he found that he had just as many cents as he had dollars when he went in

and half as many dollars as he had cents when he went in.

How much money did he have on him when he entered?

• Pocket-money, which follows exactly the same pattern.
