A new health drink has 110% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 30 mg. How many milligrams of the vitamin are in the drink

Answer 1

`p\%=(p)/(100)\\\\110\%=(110)/(100)=1.10=1.1\\\\110\%\ of\ 30mg=1.1\ of\ 30mg=1.1\cdot30mg=\boxed{33mg}`

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