Fabio's designer fashion store has become so popular that he can raise the prices every day. Each day, he raises the price of his designer pants by one dollar more than he raised it the previous day. Given that the price on Sunday the 15th was $700, what was the price on Saturday the 21st?

I think you're missing part of the question - unless I'm missing something. :-)
Also, what are the answer choices? In many instances, the best (i.e., fastest) approach involves working with the answer choices.

Cheers,
