Question

a new health drink has 130% 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?
there are \boxed{} mg of the vitamin in the drink.

Explanation:

Step1: Convert percentage to decimal

To find 130% of a number, we first convert 130% to a decimal by dividing by 100. So, \( 130\% = \frac{130}{100} = 1.3 \).

Step2: Multiply by RDA amount

The RDA for the vitamin is 50 mg. To find the amount in the drink, we multiply the RDA by the decimal we found. So, \( 50\times1.3 = 65 \).

Answer:

65
