A car dealer sells a SUV for $39,000, which represents a 25% profit over the cost. What was the cost of the SUV to the dealer?

To learn, in general, how to set up and solve "percentage" word problems, try here. :wink:

Then, using what you've learned in the lesson (along with what you know about translating the English into algebra), start with the following:

. . . . . $\mbox{dealer cost: }\, c$

. . . . . $\mbox{(selling price) is (dealer cost) plus (25%) of (dealer cost)$

. . . . . $39000\, =\, c\, +\, 0.25c$

...and so forth.
