The state university reported 1183 cases of flu in their student body for the month of January. If this was a 350% increase above the number of flu cases in the month of December, how many students had flu in December?
Let us assume the number of students having flu in December = x Number of students having flu in the month of January = 1183 Percentage increase in the number of people having flu from the month of December to the month of January = 350% Then we can write the equation as 350x/100 = 1183 350x = 1183 * 100 350x = 118300 x = 118300/350 = 11830/35 = 338 So the number of students that were affected by flu in the month of December was 338. This is the easiest way to get to the required answer.
