in one day, a store sold 2/3 as many DVDs as Blu-Ray discs. the total number of DVDs and Blu-Ray discs sold that day was 280.
how many DVDs were sold?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

where x is the number of Blue-Rays sold.

Solve for x and then calculate %282%2F3%29x.
