Of the 60 researchers in a workgroup, 40 percent will be assigned to Team A and the remaining 60 percent to Team B. However, 70 percent of the researchers prefer Team A and 30 percent prefer Team B. What is the lowest possible number of researchers who will NOT be assigned to the team they prefer?  Choices.
A) 15
B) 18
C) 20
D) 25
E) 30
I solved it by assuming 100 people and then dividing my answer in two to save time on calculations. (percentage equals number of people) In that case   40 will be in team A   60 will be in team B   The larger diff is   70 want team A so diff is 70-40=

<output>30</output>
30. At least 30 people will NOT get their wish, so for 60 researchers the same number is 18.   Answer choice 18
<result>B</result>
