My mother celebrated her birthday with a total of 60 guests. Half of the guests are women, 15 are men, and the rest are children. In the middle of the celebration, 1/3 of the men and 5 children left. How many people stayed and enjoyed the birthday celebration?
There were 60 guests / 2 = <T>divide(60, 2)=30.0 women at my mother's birthday celebration.
There were 30 women + 15 men = <T>add(30, 15)=45 men and women.
So, 60 people - 45 men and women = <T>subtract(60, 45)=15 were children.
Then, 15 men / 3 = <T>divide(15, 3)=5.0 men left.
Thus, 5 men + 5 children = 10 people left.
Therefore, 60 people - 10 people = <T>subtract(60, 10)=50 people stayed and enjoyed the birthday celebration.
