Atrailer 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

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

there are infinitely many solutions.
