In the post by @mananth, the treatment is not adequate to the problem.
Due to this reason, his solution is conceptually incorrect.
I came to bring a correct solution.
Let the cost of the ticket be x dollars before tax.
The purchase including the 7% sales tax is (1+0.07)x = 1.07x.
We have this equation
1.07x = 280 dollars.
Hence x = = 261.682243.
We round it to the closest cent.
ANSWER. The cost of the flight before the tax is $261.68.
