At the conference after everyone had shaken hands with everyone else it was found that 45 handshakes were exchanged . how many were at conference?
If ( n ) is the number of people at the conference, the total number of handshakes can be calculated using the formula ( \frac{n(n-1)}{2} ). Setting this equal to 45 gives the equation ( \frac{n(n-1)}{2} = 45 ). Multiplying both sides by 2 results in ( n(n-1) = 90 ). Solving the quadratic equation ( n^2 - n - 90 = 0 ) yields ( n = 10 ) (since the negative solution is not applicable). Thus, there were 10 people at the conference.
