10,030 this is basic math you just have to multiple the amount the manufacture in one day by how many days you are measuring.
For (8, 16): 3(8) - 8 = 24 - 8 = 16 [solution]
For (3, 4): 3(3) - 8 = 9 - 8 = 1 [not a solution]
For (-6, -26): 3(-6) - 8 = -18 - 8 = -26 [solution]
For (-10, -38): 3(-10) - 8 = -30 - 8 = -38 [solution]
