Question

Adult = $5 , child = $2

There were twice as many children as adult as the concert.The total amount of money collected was $ 1080. How many many people were there at the concert?

Answer 1

x = adult places

2x = children’s places

5x+2x*2 = 1080

5x+4x=1080

9x = 1080

x = 120

120 adult places = 120*5=$600

240 children’s places = 240*2=$480

How many many people were there at the concert : 360
