One serving of oatmeal provides 16% of the fiber you need daily. you must get the remaining 21 grams of fiber from other sources. how many grams of fiber should you consume daily?

Daily = D
O = one serving
O = .16D
21g = (100-16)%D = 84%D
21g = .84D
21/.84 = D
D = 25g

Hope this helps.

 fiber recommendations are 30 to 38 grams a day for men and 25 grams a day for women between 18 and 50 years old, and 21 grams a day if a woman is 51 and older.

Just a question- could you organize the data better? i just cannot tell which number are for which bakery. i will be happy to answer this question if you could do this for me! : )
