Question

At the start of the football game, there were 840 fans in the stadium. It began to rain during halftime, so 10% of the fans went home.

During the 3rd quarter of the game, the visiting team scored five touchdowns, so 25% of the remaining fans went home.
How many fans were in the stadium after the 3rd quarter?

Answer 1

After the third quarter there were 567 fans in the stands
840x.90(total-part)=756 fans at 1/2 time
756x.75= 567 fans after the third quarter
