Each month, a phone company charges $20 for 500 minutes of talk time plus $0.45 for each additional minute. unlimited texting cost $30 more. write an expression to show the cost of a talk-and-texting plan for one month, given x minutes over 500

Hiya!

Let's assume that you have the unlimited texting plan, which is $30. You also have 500 minutes which is $20. Your total is $50 for one month.

We can assign variables to represent this in our equation. 'u' can be for unlimited texting, 'm' can be minutes, 'a' can be additional minutes, and 'o' can represent one month.

If you plug all of this into an equation, it'll look something like this:

50o=30u+(20m+.45a)

Hopefully this checks out :p Check with your math teacher to make sure this is right.
