Answer 2

Answer: x(1-0.33) or 0.67 x

Explanation:

The old soup recipe contained sodium per serving = x mg

According to the question,

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

That is, the Sodium per serving in the new soup = the Sodium per serving in the new soup - 33% of the Sodium per serving in the new soup

= x - 33% of x

= x - 0.33 x ( since 1% = 0.01 ⇒ 33 % = 0.33 )

= x(1-0.33)

= x(0.67)
