Question

A new health drink has 180​% 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

90 mg

Explanation:

1 rda = 100% = 50 mg

180% = x

100/180 = 50 / x Cross multiply

100x = 180 * 50

100x = 9000 mg Divide both sides by 100

100x/100 = 9000/100

x = 90

The drink contains 90 mg
