The weight of the load varies directly with the number of boxes in the load a loaf of 18 boxes ways 390 pounds what does a load of 12 Boxes Weigh

Answer 1

Hi Elena,

Since the weight and the number of boxes vary directly, we can determine the constant, k, that would exist when two quantities vary directly:

Weight = k • number of boxes

390 = k • 18

390/18 = k

21.6667 = k

To determine the weight of 12 boxes, we just need to multiply by the constant, k:

weight = 21.6667 • 12

weight = 260 pounds
