Ten dollars, 25% of forty.

If I read it correctly, the question is how much you save by buying on sale.

$10 saved

you could set it up as follows 40$/1 AS X$/0.25 then you cross multiply and solve for X

OpenStudy (anonymous):

The discount is 25% of the price. In this case, and lots like it, of means multiply.
