Question

1. You can buy a 6-hour phone card for $5.00, but the fine print says that each minute actually costs you 1.5 minutes of time. What is the equation that models the number of minutes left on the card compared with the number of minutes you actually talked? What is the graph of this equation?

Answer 1

divide 5.00 by 1.5 and you get (it's pretty long) 3.3333333333333333333333333333333
