What is the maximum acceptable size for the dimension written as 7.439 inches plus .007 inches minus .003 inches?

Explanation:
Asymmetric tolerances set different allowable extents above and below the nominal size. Here, the dimension is 7.439 inches with a plus tolerance of 0.007 inches and a minus tolerance of 0.003 inches. The largest permissible size comes from adding the positive tolerance: 7.439 + 0.007 = 7.446 inches. The smallest permissible size would be 7.439 - 0.003 = 7.436 inches, so the acceptable range is 7.436 to 7.446 inches. Therefore, the maximum acceptable size is 7.446 inches.
