You are a representative for a cell phone company and it is your job to promote different cell phone plans. Your boss asks you to visually display two plans and compare them so you can point out the advantages of each plan to your customers.

Question

-Plan A costs a basic fee of $30 per month and 10 cents per text message
-Plan B costs a basic fee of $50 per month and 5 cents per text

1. What are the variables in the problem and the equations for Plan A and Plan B?
2. When are Plan A and Plan B the same price based on the number of texts sent? Explain how you determined this.
3. Determine when Plan A is a better plan to go with (based on the number of texts someone sends). Explain how you determined this.
4. Determine when Plan B is a better plan to go with (based on the number of texts someone sends). Explain how you determined this.
5. If you generally send 100 tests a month, what is the better plan for you? Explain how you determined this.

I would so greatly appreciate any help with this.

Answer 1

A = 30 + 0.10m
B = 50 + 0.05m

see what you can do with those equations.
