Question

A stadium holds 51000 seats seats sell for 25 in section a 20 is section b and 15 in section c the number of seats in section a equals the total number of setas in section b and c suppose the stadium takes in 1,090,500 from each sould out event how many seats does each section hold

Answer 1

Answer:a = 25500 , b= 14100 , c= 11400

a+b+c= 51000 .............(.1)

25a+20b+15c= 1090500....(2)

a= b + c

2a = 51000

so

a = 25500

b + c = 25500 or

c  = 25500-b

using 2

25x 25500 + 20Xb+ 15( 25500-b) = 1090500

5b =1090500-40x25500

5b = 1090500-1020000

5b = 70500

b=14100

c=25500-14100

c=11400
