Vin pays verizon a monthly fee of $55 for his cell phone. he also pays $0.30 for each text.
if his cell phone bill for october is $90 .10 how many text messages did he send?
part a: write an equation to solve the problem

part b:
show the steps you took to solve the problem
part c: explain how you found how many text messages vin sent in the month of october.

Part A: 

90.10 = 0.30x + 55

Part B:

Subtract 55 from both sides

 90.10 = 0.30x + 55
-55                   -55

35.10 = 0.30x

Next, you need to isolate the variable so you must divide both sides by 0.30. You should get:

117 = x

Vin sent 117 text messages that month.

Part C: (this part is a bit unclear, though I will try to answer it as best I can)

I found the number of text messages Vin sent in the month of October by creating an equation that outlined his bill and solving it.
