Answer:
1300 kids attended the circus
Step-by-step explanation:
Using one variable, we can set up an equation to solve for the amount of kids that attended the circus. Using 'x' for the amount of adult tickets, we can use '2x' for the amount of children's tickets since the problem says there were 'twice as many kids than adults'. With the ticket prices and total sales:
6x + 2.5(2x) = 7150 (distribute) 6x + 5x = 7150
Combine like terms: 11x = 7150
Divide by 11: 11x/11 = 7150/11 or x = 650
Since 650 represents the amount of adult tickets, 2x is the amount of children's tickets: 2(650) = 1300 childrens tickets
