Julia is allowed to watch no more than 5 hours of television a week. So far this week, she has watched 1.5 hours. Write and solve an inequality to show how many hours of television Julia can still watch this week.

20.

You are a member of your local movie theater’s club. Every time you see a movie at the theater, you earn 2 advantage points. When you earn 100 points, you get a free movie pass. Currently, you have 40 advantage points.

Write an equation to model the number of movies m you have to watch before you earn a free movie pass.

Solve the equation. Show your work.

21.

Write an equation with a variable on both sides of the equal sign that has infinitely many solutions. Solve the equation and explain why it has an infinite number of solutions.

My answers:

19.

T<5

T - 1.5 < 5 - 1.5

T = 3.5

20.

40 + 2m = 100

40 + 2m - 40 = 100 - 40

2m = 60

2m ÷ 2 = 60 ÷ 2

m = 30

21. ????????
