Answer 1

Answer:

  2 medium bags

Step-by-step explanation:

Using estimates of 8, 12, and 20 for the number of cups in each bag size, you can see that the number of each size needed is ...

  floor(30/8) = 3 . . . small bags

  floor(30/12) = 2 . . . medium bags

  floor(30/20) = 1 . . . large bag

3 small bags will contain 3(8 1/4) = 24 3/4 cups.

2 medium bags will contain 2(12 3/4) = 24 3/2 = 25 1/4 cups

1 large bag will contain 20 7/8 cups.

The closest Natalie can get without exceeding the container size is with purchase of 2 medium bags.

Additional comment

The best solution would be to purchase 1 small and 1 large bag, for a total of ...

  8 1/4 +20 7/8 = 28 9/8 = 29 1/8 . . . cups

However, that purchase is not multiple bags of the same size.
