A cell phone company charges a $20 flat fee plus $0.05 for every minute used for calls. 1.Make a table of values from 0 to 60 minutes in 10- minute intervals that represent the total amount charged. 2.Write an algebraic equation that could be used to represent the situation. 3.What do the unknown values in your equation represent? 2

1.Make a table of values from 0 to 60 minutes in 10- minute intervals that represent the total amount charged : Creating and Graphing Linear Equations in Two Variables 3 Minutes usedTotal amount charged ($) (0.05) = (0.05) = (0.05) = (0.05) = (0.05) = (0.05) = (0.05) = 23.00

2.Write an algebraic equation that could be used to represent the situation. y = 0.05x What do the unknown values in your equation represent? x represents the number of minutes used, and y represents the total amount charged : Creating and Graphing Linear Equations in Two Variables
