Best ResponseYou've already chosen the best response.0A cell phone plan has a monthly cost that is shown in the table below. What is the correct statement regarding the average rate of change during the 40minute time of talk? Total minutes of talk time Monthly cost of cell phone 0 $14.95 10 $15.95 20 $16.95 30 $17.95 40 $18.95 The average rate of change is $1.00, meaning that for every ten minutes of talk time, the monthly bill increases by $1.00. The average rate of change is $1.00, meaning that for each minute of talk time, the monthly bill increases by $0.10. The average rate of change is $0.10, meaning that for every ten minutes of talk time, the bill increases by $0.10. The average rate of change is $0.10, meaning that for each minute of talk time, the monthly bill increases by $0.10.

Best ResponseYou've already chosen the best response.0ok. starting from the top, the rate of change is \[\frac{ y_2y_1 }{ x_2x_2 }\] Pick two points from your table, the y's are the cost and the x's are the minutes
