Answer:
4
Step-by-step explanation:
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.
Wrong because you need to add the -2 to the 8.... I hope this helps
Multiply both sides by 10...
So u = 50/11 = 4.5454... = 4.55
Yes (I guess)
(-1, 2) Lies on a line so im guessing it is...
