A new soup recipe contains 33\%33%33, percent less sodium per serving than the old soup recipe. The old soup recipe contained xxx milligrams of sodium per serving.

Answer 1

Answer:

The expression 0.67x and (1 - 33/100)x each could represent the amount of sodium per serving, in milligrams, in the new soup. Guaranteed correct. Straight from Khan Academy's explanation.

Step-by-step explanation:

The old soup recipe contains x milligrams of sodium per serving. The new recipe contains 33% less sodium per serving than the old recipe.

This means each serving of the new soup recipe contains 33%x milligrams less sodium than each serving of the old soup recipe.

That means each serving of the new soup recipe contains x - 33%x milligrams of sodium.

Because 33% means 33 per hundred, we can write it in equivalent forms.

33% = 33/100 = 0.33

Let's find equivalent ways of writing the amount of sodium in each serving of the new soup recipe.

x - 33%x = x - 33/100x = x(1 - 33/100) = x(1 - 0.33) = x(0.67) = 0.67x

Hope it helps!
