I hope this helps!
Instead of using an = sign we use

becuase its less than or equal to 100 dollars.
The equation of the line is y=10x+7
sub in 100 for y and the inequallity sign
10x+7

100
solve so x is isolated
10x

93
x

9.3
technically the answer is 9 because you cant buy a fraction of a CD
1.D 2. A 3.C 4.D
1 Is the monomial as it only contains one expression.
2. Is the difference of squares because something squared minus something squared.
3. Is standard because it is of the form

4. We know D is the not the monomial simply because its power is negative which means it does not fit the definition of a polynomial.
