at a concert 2/5 of the people were men, there were 3 times as many women as children, if there were 45 more men than children, how many people were there at the concert
people: p
men: 2/5 p
children: c
women: 3c
men: 2/5 p = c+45
people = m+w+c = 2/5 p + 3c + c
so, p = 2/5 p + 4c
3/5 p = 4c
2/5 p = c+45
c=27
p=180
180 people at the show.
so, women=81
men=72
