Bud's cheeseburger and fries contained 1310 milligrams and 350 milligrams of sodium, respectively. Together they contained 66.4%
Serhud [2]

Answer:

The recommended daily intake of sodium for a 2000 calorie diet is 2500 mg.

Step-by-step explanation:

In order to calculate the daily intake of sodium we first need to calculate the mass of sodium present in both snacks, this is given by their sum.

\text{total sodium} = 1310 + 350 = 1660 \text{ mg}

We can now apply a rule of three for which the total sodium from the snacks is related to 66.4% in the same proportion as "x" mg, which is the value we want to know, is related to 100%. So we have:

\frac{1660}{x} \frac{mg}{mg} = \frac{66.4\%}{100\%}

66.4*x = 1660*100\\x = \frac{166000}{66.4} = 2500 \text{ mg}

The recommended daily intake of sodium for a 2000 calorie diet is 2500 mg.
