A cell phone plan costs $29.99 a month and includes 250 local minutes. Each minute over 250 costs the customer $0.15, and roaming costs an additional $0.45 a minute. A customer used his cell phone 280 minutes last month, 65 of which were made outside of the home coverage area. If taxes at 12% were added to the bill, how much was the customer's cell phone bill last month?
