Let x be equal to the number of minutes
Then we have the following equation:
(0.03)x + 29.95 = 38.95
(0.03)x = 9.00
x = 300
Answer: x = 300 minutes for the month of october
You can check to see if this is correct by substituting x = 300 back into the original equation:
(0.03)x + 29.95 = 38.95
(0.03)(300) + 29.95 = 38.95
9 + 29.95 = 38.95
38.95 = 38.95 :)
