In 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?
A.1,200
B.2,880
C.3,280
D.4,200

40% of 3000 = 1200 and it makes sense because 1500 is half and 40% should be a little lower than that. If the first week is 3000 people, you basically add 1200 x 2 to get 2400, but that answer is not on here, so I just think to round it to 2880 so I guess B.

Im not in middle school, Im in elementary school so I'm not that smart, Im just testing my knowledge.
