A phone company charges a sign-up fee of $3.50, plus $x for every hour the phone is used. If Brian talked on the phone for 12 hours and paid a total of $75.50, which of the following equations can be used to find, x, the hourly rate of the phone plan?

• 3.50 + x = 75.50 
• 3.50 - x = 75.50 
• 75.50 + 12x = 3.50 
• 3.50 + 12x = 75.50
