Question

N a recent flu epidemic, the number of flu cases increased by 40% each week. There were 3,000 flu cases during the first week of January. How many more people were affected by the flu during the third week of January than during the first week?

Answer 1

2,880 people

Explanation:

Week 1: 3,000 cases

Week 2: 0.4 * 3,000 = 1,200. 1,200 + 3,000 = 4,200

Week 3: 0.4 * 4,200 = 1,680. 1,680 + 4,200 = 5,880

5,880 - 3,000 = 2,880
