A cell phone company charges $60.00 a month for up to 1 gigabyte of data. The cost of additional data is $0.05 per megabyte. If d represents the number of additional megabytes used and c represents the total charges at the end of the month, which linear equation can be used to determine a user's monthly bill?  

• c = 60 - 0.05d

• c = 60.05d

• c = 60d - 0.05

• c = 60 + 0.05d
