In the scenario above, does it ever make sense to buy into the cinephile's club? If so, under what conditions would it be cheaper to join the club? Be as specific as possible.

How many solutions does the equation

Pitanje 2

2.

Component A costs $10 per unit, and Component B costs $14 per unit. Which equation will help solve for the number of units, u , of Component A we need to mix with 3 units of Component B to create a mixture with an overall price of $13 per unit?

Pitanje 4

4.

Which of the following equations are contradictions (which have no solutions)?

4x-3=\frac{1}{3}(12x-9)

\frac{3}{2}x+1=3(\frac{x}{2}+1)

9x+1=3x+1

\frac{3}{4}(x+4)=\frac{9}{12}(x-1)

3(x+2)=8(2x-1)

Pitanje 5

5.

The local movie theater has a special "cinephile" club. Instead of paying $14 for every ticket, you pay $34 a month to be a member of the club. You get one free movie each month, and you pay only $9 per ticket after that. Which equation will help solve for the number of movies, m, you must go to in a month to make the cost without club membership equal to the cost with the club membership?

14m=34+9m

14m=34+9(m-1)

9m=14m+34

9(m-1)=14m+34
