Question: The number of coronavirus cases in a certain country was 300 infections per day during the first wave. However, the number of cases increased by four times more per day as a new coronavirus variant started infecting people in a second wave. What was the total number of infections during the second wave in 2 weeks?
Answer: When the number of cases increased by four times more per day during the second wave, there were 4 * 300 = 1200 more infections per day than during the first wave. The total number of infections during the second wave per day was 1200 + 300 = 1500. For two weeks with 14 days, the number of me infections was 14 * 1500 = 21000. The answer is 21000.

Question: Ivory and Brayan are doing school projects with a tight deadline and have to stay up late to complete everything. They prepare coffee to help them stay focused. If Brayan drinks twice as much coffee as Ivory, and Brayan drinks 4 cups of coffee in an hour, calculate the total number of cups of coffee they drink together in 5 hours.
Answer: If Brayan drinks 4 cups of coffee in an hour, twice what Ivory drinks, then Ivory drinks 4 / 2 = 2 cups of coffee in an hour. Together, they drink 4 + 2 = 6 cups of coffee in an hour. After 5 hours, they will drink 5 * 6 = 30 cups of coffee together. The answer is 30.
