~ Red section seats 200 people
~ Blue section seats 20 fewer people than the red section
~ Green section seats 2 times as many people as the blue section

What is the total number of people who can sit in the stadium when it is full?
How did you get your answer?

Answer 1

Red section (full)=200 people

Blue section (full)=200-20=180 people

Green section (full)=2×blue section ( full)=2×180=360 people

Stadium (full)=(200+180+360) people=740 people

Answer 2

740

Explanation:

R = 200

Blue = 200-20 = 180

Green = 2(200-20) = 2( 180) = 360

200 + 180 + 360

740
