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?

2400 newly affected from first week to third week. 5400 total.

Step-by-step explanation:

40% of 3,000 is 1200. so 1200 new people will be affected in the second week. In the third week another 1200 will be affected making it 2400 since the first week. Now, in total on the third week there is 5400 affected in total.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
