Answer to your question is:
B. 4
Explanation:
2 + 5 + 4 + 1 + 8 = 20
20 ÷ 5 = 4
How many ounces are in a pound? 16! SO 16 times 4 = 64. So Nancy needs 64 ounces in all. So 28 plus 10 = 38 that's still not enough, so lets add some more 38 plus 10 = 48 still not enough, add some more 48 plus 10 plus 10 = 68. So lets add up how many bags we need. So in all with her 28 that she already has, we need 4 bags.
