Equation is $25 x + 30 = 130$

Explanation:

The trailer was used for $25$ miles.

Let charges per mile for trailer be $x$, in dollars, per mile

then charges for $25$ miles are $25 \times x = 25 x$

As rent per day is $30 and total charges are $25 x + 30$As total charge was $130

equation is $25 x + 30 = 130$
