15) webflix decides to compete with netflix. instead of $8 per month for unlimited streaming of movies, webflix charges $3.50 per month for a membership and $0.45 to watch a movie. a) how many movies can you watch for $7.10? b) if you watched 17 movies last month, how much did you spend?

Problem B

Equation

Total = 3.50 + Number of movies watched * 0.45

Givens

Total = 17 movies.

Substitute and Solve.

Total = 3.50 + 17*0.45

Total = 3.50 + 7.65

Total = 11.15 Answer <<<<<

Conclusion: Stick with Netflix.

Problem A

Givens

Total = 7.10

Cost per movie = 0.45

Base Cost 3.50 for no movies.

Equation

Let the number of movies you can watch = n

Total = Base Cost + n*0.45

Substitute and solve

7.10 = 3.50 + n * 0.45 Subtract 3.50 from both sides.

7.10 - 3.50 = n*0.45

3.60 = n* 0.45 Divide by 0.45

3.60/0.45 = n

8 = n <<<< Answer

You can watch 8 movies.

Edit

Multiply both sides by 3.60

You are done. It's like solving something like

3x + 4 = 13 You would subtract 4 first and then divide by 3
