At the start of the football game, there were 640 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?

The number of fans remaining after the 3rd quarter=432 fans

Step-by-step explanation:

Initial number of fans in the stadium=640

The number that went home by halftime=10% of Initial number=(10/100)×640=64 fans

Remaining fans=Initial number of fans-the number that went home

Replacing;

Remaining fans=(640-64)=576 fans

At 3rd quarter=25% of remaining fans left=(25/100)×576=144 fans

At 3rd quarter 144 fans also left

The remaining at 3rd quarter=(Remaining fans at halftime-Fans that left at 3rd quarter)

(576-144)=432 fans

The number of fans remaining after the 3rd quarter=432 fans
