Answer 1

55mg

Explanation:

In order to calculate the total number of vitamin mg are in the drink we first need to turn the percentage of vitamin mg in the drink into a decimal. We do this by dividing the percentage by 100 like so...

110 / 100 = 1.1

Now that we have the decimal value of the percentage we simply multiply it by the recommended daily allowance​ (RDA) for this vitamin.

1.1 * 50mg = 55mg

Finally, we can see that the new health drink contains 55mg of this vitamin.
