Question

A new health drink has 110​% of the recommended daily allowance​ (RDA) for a certain vitamin. The RDA for this vitamin is 50 mg. How many milligrams of the vitamin are in the​ drink?

Answer 1

55 mg of the vitamin is in the drink.

Explanation:

1. Create a proportion based on the word problem. In this case, the proportion is:
   `(110)/(100) = (x)/(50)`.
2. Find what you must divide by to get from 100 to 50, which is 2.
3. Divide 110 by 2 to solve for x, making the proportion equal.

`(110)/(100) =(55)/(50)`, which means 55 mg of the vitamin is in the drink.

Answer 2

110% of 30 is 30*(110/100)=30*1.1=33 mg
