The answer is 6 People. You make the two equations first 12.99x and 8.99x+20. And then make them equal each other 12.99x = 8.99x+20. Then you use algebra to solve for the x and you get an answer of 5. That is the number of people that would cause the two prices to break even (be the same price). So in order for the group rate to be the better deal you need 6 people to attend.
The answer is 35.
Reasons : 2*3 = 6. 6•6= 36-1= 35.
This type of parabola opens either to the left or to the right. The negative makes it open to the left.
