Question 57145: How do I compute the implied DV for sodium in soda?
For exmaple, a nutrition label listd 15(mg) of sodium representing 1% of the recommended daily value (DV) based on a 2,000 calorie/day diet. However, someone figured this implied that the DV came out to 1500(mg) per day. What were the steps used to calculate the answer?

Part/Whole = Percent/100 [Use the formula for percents]
15/DV=1%/100 [Plug-in the values]
15/x=1%/100 [Cross-multiply]
(15)(100)=(1%)(x)
1500/1%=x [solve for x]
1500=x
.
Check by plugging all of the values back into the original equation.
