Answer: x(1-0.33) or 0.67 x
Step-by-step 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)
