One-third cup of black beans provides 20% of the potassium you need daily. You must get the remaining 1,360 milligrams from other sources. How many milligrams of potassium should you consume daily?

Respuesta :

5×20%=100% so 1360mg is 80% of the daily requirement. The total requirement is 1360/0.8=13600/8=1700 mg.

80 percent of needed milligrams is 1360

so

1360/.80 = x/1  

1700 milligrams or 1,700 milligrams of potassium
