Answer:
$64.50
Step-by-step explanation:
First you need to find how much the fee is from the information on the month of September:
1.) Find out how much the minutes cost so you can subtract that number from the total of the bill to find how much the fee was
[tex]120*.30=[/tex]$36
$51 - $36 = $15
This means the monthly base fee is $15
Now all you have to do is figure out how much 165 minutes cost then add the monthly fee of $15
[tex]165*.30=[/tex] $49.50
$49.50+$15= $64.50
