Question

One-Half cup of black provides 15% of the potassium you need daily. You must get the remaining 2890 milligrams from other sources. How many milligrams of potassium should you consume daily?

Answer 1

Since the remaining 2890 milligrams is 100-15=85 percent of the potassium you need, we need to find how much 100% is. We can do this by dividing it by 8.5 to get 10 percent, and multiplying that by 10 to get 100%. This is 340*10=3400
