A trailer is rented at $30 per day plus a charge per mile of use. The trailer traveled 25 miles in one day and the total charge was $130. Which equation can be used to find the charge x, in dollars, per mile traveled?

30x + 25 = 130

30x + 25x = 130

30 + 25x = 130

30 + 25 = 130x

30  + 25x = 130 is correct

30 epresents the "fixed" charge per day and 25x is the variable charge based on the miles driven
