Final answer:
C) Heaviest approved bag: 16 + 0.3 = W, Lightest approved bag: 16 - 0.3 = W. The correct equation to find the heaviest and lightest approved bags is: Heaviest approved bag: 16 + 0.3 = W, Lightest approved bag: 16 - 0.3 = W.
Step-by-step explanation:
The correct equation to find the heaviest and lightest bag the machine will approve is:
Heaviest approved bag: 16 + 0.3 = W
Lightest approved bag: 16 - 0.3 = W
The heaviest approved bag is determined by adding 0.3 to the desired weight of 16 ounces, while the lightest approved bag is determined by subtracting 0.3 from the desired weight. This equation takes into account the tolerance of .3 ounces more or less than the desired weight for a bag to be approved.
