#### 8.771. A virologist is testing a new antiviral compound on a culture of 1000 virus particles. After applying the compound, 60% of the viruses are neutralized in the first hour. In the second hour, 30% of the remaining viruses are neutralized. How many virus particles remain active after two hours?

Title: Understanding Antiviral Efficacy: How Many Virus Particles Remain After Two Hours? In the fight against viral infections, tracking how antiviral compounds reduce viral load is crucial for evaluating treatment effectiveness. Recent experiments using virtual virology models showcase a clear pattern: antiviral treatments significantly reduce virus particle count over time. Let’s explore a detailed breakdown of one such test involving 1,000 virus particles. ### The Scenario: A Trial with a New Antiviral Compound In a controlled laboratory setup, a virologist administers a new antiviral compound to a culture containing 1,000 virus particles. The treatment is applied and monitored over two consecutive hours:
