Monthly cost of cell phone for 0 minutes is $19.95 and for 40 minutes of talk is $21.95. It means that average rate of change ( increase of monthly cost for each minute of talk time ) is: ARC = ( 21.95 - 19.95 ) / ( 40 - 0 ) = 2.00 / 40 = $0.05. C ) The average rate of change is $0.05, meaning that for each minute of talk time, the monthly bill increases by $0.05.

N=9
5(n+11)= 45+55
Since We times first before adding
5(n+11)=100
5n+55=100
Subtract 55 from each side
5n=45
Then divide
N=9
