$415 is only enough to buy at most one box of 20 DVDs for $230 from the first supplier.

If the number of boxes of 20 from the first supplier is 1, then there is $185 left; since the boxes of 10 from the second supplier cost $180, it is possible to buy one box from each supplier, spending a total of $410 and getting 30 DVDs.

If no boxes of 20 are bought from the first supplier, the maximum number of boxes from the second supplier that can be bought is 2, giving 20 DVDs for $360. That is fewer DVDs, with more money unspent, than the other option.

ANSWERS: one box of 20 and one box of 10, for a total of 30 DVDs, with a cost of $410.
