Question

The doctor recommended Avery has 11 milligrams of iron per day. By how much did she exceed the doctor’s recommendations if she ate a bowl of shellfish containing 16 milligrams of iron?

Answer 1

I believe Avery exceeded the recommendation by 5 milligrams.

I hope this helped :)

Answer 2

5 mg

Explanation:

Let

• x = milligrams of iron recommended per day = 11 mg

• y = milligrams of iron in a bowl of shellfish = 16 mg

The excess in the consumption of iron is the difference between what she ate and what was recommended. Then, the appropriate algebraic operation is the subtraction.

y - x = 16 mg - 11 mg = 5 mg
