The transformation is merely a translation of points vertically and horizontally. The original triangle must have its original coordinates. All you have to do is subtract 1 from their x-coordinate, and add 2 units to their y-coordinates. For example, if the original coordinate is (1,2), then the translated point would now be (0,4). Once you get all the translated points, you can plot them as the new translated triangle.
I think about 52 bags 2 kilometers = 2,000 grams 2, 000/ 38 = 52. repeated decimal(which would be the amount leftover) I believe the answer would be 52 bags.
