tues. but I don't understand.? Here's the group of questions for the review....I just don't understand..help please?
1. Set up a linear system consisting of two equations. Assume you will talk for a minimum of 500 minutes. The first equation would be for Talks-A-Lot. The total cost, y, equals the base fee plus cost per minute times the number of minutes over 500. The second equation would be set up just like the first, only you need to use the information for the ChatAway Company.
2. Solve the linear system using the substitution method. Please make sure to solve for x and y both (show all work).
3. Answer the questions, in a complete sentence.
1. How many minutes would you have to talk over the 500 minutes for the cost to be the same with both companies?
2. What would be the cost when the minutes are the same?
4. If you plan to talk for 700 minutes, which company should you hire? Please show your total cost for Talks-A-Lot and ChatAway Company to prove your answer.
