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.
In all of these cases, y=x+2.
Ann = 3 CD's
Ann = 2x-3
5 = 2x-3
x= CD's bob has
5 = 2x-3 is the equation
to solve
add 3 to each side
8 = 2x
divide by 2
x =4
bob has 4 CD's, ann has 5
The terms 
and 
can be added to 
to result in a monomial.
Step-by-step explanation:
Given term is;
A monomial is an algebraic expression that consists of only one term.
So in the given expressions, we will add the terms which have same variables as given terms.
Given options are;
The terms and can be added to to result in a monomial.
