Answer:
58.5 mg of the vitamin is in a drink.
Step-by-step explanation:
1. We know that a health drink = 130% of the daily allowance RDA for a certain vitamin "x"
2. In the RDA for a certain vitamin "x" = 45mg
3. Once put them together > 130% of 45 = (the missing) mg in the drink.
Now that we have that out of the way time to solve...
[tex]130 = \frac{130}{100} = 1.3[/tex] next, multiply 45 by 1.3 >> 130 of 45 >> 1.3(45) = 58.5
I hope this help you whether you still need it or not.
