Reasoning and answer: Four hats, each with three stripes, is 4 * 3 = 12 stripes. Three hats with four stripes each is 3 * 4 = 12 stripes. Six hats with no stripes is 6 * 0 = 0 stripes. And two hats with 5 stripes each is 2 * 5 = 10 stripes. The combined total number of stripes Vaishali has on all of her hats is 12 + 12 + 0 + 10 = 34 stripes.

The first movie was 2 * 60 = 120 minutes. So this movie is 120 * .6 = 72 minutes longer. So this movie is 192 minutes. It also cost 50 * 2 = $100 per minute to film. So it cost 192 * 100 = $1920.
The answer: 1920
