alleryStart learning →One serving of cereal has 85 mg of potassium, which is 2% of the recommended daily amount. What is the total recommended daily amount?
A1,700 mg
B4,250 mg
C425 mg
D42,500 mg
Answer & Solution
Correct answer: B. 4,250 mg
1. Change 2% to a decimal: 0.02.
2. Since 85 mg is 0.02 times the total amount, divide 85 by 0.02 to undo the multiplication.
3. 85 divided by 0.02 equals 4,250.
4. So the total recommended daily amount is 4,250 mg.
