A hammer and a nail cost $1.10, and the hammer costs one dollar more than the nail. How much does the nail cost?
Interesting! Can you recommend a recipe that uses expensive and cheaper ingredients?
I'm not sure, as I don't have a database of recipes. However, maybe you could try searching for a recipe that involves truffles and potatoes, since truffles are an expensive ingredient and potatoes are relatively cheap.
