A clothing store paid an import tax of $40 on a shipment of $800 worth of silk scarves. The import tax rate is always the same. What would be the value of silk scarves that have import tax of $100?

the answer is counterpoint.

counterpoint definition: "the art or technique of playing a melody or melodies in conjunction with another, according to fixed rules."

counterpoint is present in a lot of baroque music- such as bach (notably his wtc prelude and fugues) and scarlatti, but can also be found in music by mozart, beethoven. it can even be found in music as modern as john williams!
