The price per movie is much lower for the boxes of 25, so the manager should buy as many of those as possible.

At $240 per box, he can only buy one of them with $415.

Buying one box of 25, he has $415-$240 = $175 left, which is enough (just barely) to buy one box of 14, since those boxes cost $170 each.

So he can buy one box of each, for a total of 39 movies, for a total of $410.

If he doesn't buy any of the boxes of 25, his $415 is only enough to buy two boxes of 14, giving him only 28 movies. So the one box of each is the better purchase.
