PastriesNumber Theory Level 2
Both John and Paul like pastries, but they realize that they haven't got enough money: to buy one pastry, Paul needs more 53 cents and John needs more 48 cents. Even if they put together their money they can't buy one pastry.
With this information you can't know unambiguously the cost of a single pastry, but you can get the maximum cost of a pastry. Write this cost in dollars.
