Problema Solution
the junior class is electing class officers. You are running for president. You know that you have support of one-fourth of the 610 member class. If there is one other candidate for president, what is the least number of additional vote you mut get to be assured of a win?
Answer provided by our tutors
We will assume that the one that had more votes wins.
One-fourth of the 610 member class is: (1/4)610
Let x represent the additional vote you must get to win:
(1/4)*610 + x > 610/2
........
........
x > 152.5
Since x needs to be integer follows that the least number of additional vote is 153 votes presuming all 610 members voted and all votes are valid.
