The number of servings, S of oatmeal varies directly as the net weight, W of the container. There are 30 servings in a 42 oz box of oatmeal. How many servings does a 60 of box of oatmeal contain?

Answer 1

Hi Breanne,

When you are told the the number of servings, S varies directly with the weight, W that meant that

S = kW i.e that S and W are linearly related andwe just have to figure out what k is. You were also told that

when W= 42 oz, S=30 so if we sub these values for S and W we can calculate k , 30=k*42 so k=30/42=.714 servings/oz

So now we have all we need to answer the question that was asked "how many servings does a 60 oz box contain?"

S=.714*60= 43 servings (approx)

Hope this helps
