Question

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

Answer 1

30 + 25x= 130, the 30 is a one time charge since this is only asking about one day, we don't how much it is per mile so that is X and if you traveled 25 miles it would be 25 times X, which is whatever the cost per mile is, equals the total amount the person paid which is 130
