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?

Respuesta :

Answer:

Option B

(B) 2880   Hope this helps

Step-by-step explanation:

the total number of people affected by flu during

the 2nd and 3rd week of January,  1200 + 1680  = 2880                                              

By the third week in January there would be 2880 people affected by the

flu

The number of people that would be affected by the flu in the third week of January can be determined with this formula:

FV - PV = increase of the number of affected people

FV = P (1 + r)^m

  • FV = Future value  

  • P = Present value = 3000
  • R = rate of increase = 40%
  • m = number of weeks = 3

3000 (1.4)^3 = 5880

Increase in the number of affected people = 5880 - 3000 = 2880
