Stella is on a heart healthy diet where she must keep track of the amount of sodium she consumes each day. According to the package of chips in her lunchbox, they contain 150 mg of sodium. If this represents 15% of her recommended amount of sodium per day, what is the amount of sodium recommended for her diet

Let x be the recommended amount of sodium for Stella's diet.

According to the information given, 150 mg is 15% of the recommended amount: x * 0.15 = 150 mg.
Simplifying the equation, we have x = 150 mg / 0.15 = 1000 mg.
Therefore, the recommended amount of sodium for Stella's diet is 1000 mg. Answer: \boxed{1000}.
