A) $\frac{65}{100}x$
B) $0.65x$
C) $1.35x$
D) $1.65x$
E) $3.35x$
The amount of sodium in the new soup recipe is $100\% - 35\% = 65\%$ of the amount of sodium in the old soup recipe. So, the amount of sodium in the new recipe is $\frac{65}{100}x=\boxed{\textbf{(A)}\ \frac{65}{100}x\text{ and }\textbf{(B)}\ 0.65x}$.
A new soup recipe contains 335, percent less sodium per serving than the old soup recipe. The old soup recipe contained x milligrams of sodium per serving.
Which of the following expressions could represent the amount of sodium per serving, in milligrams, in the new soup recipe?

NO!! This are the options.

A. 0.33x
B. x - 33
C. 0.67x

Choose 2 answers:
A. 0.33x
B. x - 33
C. 0.67x
D. x - 33x
E. (1 - 33/100) x
To find the amount of sodium per serving in the new soup recipe, we need to subtract 33 percent from the old amount. This can be written as $\left(1 - \frac{33}{100}\right)x.$ Simplifying this expression gives $\left(\frac{100 - 33}{100}\right)x = \frac{67}{100}x.$ Therefore, the correct expressions for the amount of sodium in the new soup recipe are $\boxed{\textbf{(C)}\ 0.67x \text{ and } \textbf{(E)}\ \left(1 - \frac{33}{100}\right)x}.$

Florencia's hair was only 75% of its original length after the haircut.
This can be expressed as $0.75h$, where $h$ represents the original length of her hair.
Additionally, we can also express this as $(1 - \frac{75}{100})h$. Simplifying this expression gives $(1 - \frac{3}{4})h$, which is equivalent to $\frac{1}{4}h$.
Therefore, the correct expressions for the length of Florencia's hair after the haircut are $\boxed{\textbf{(D)}\ 0.75h\text{ and }\textbf{(E)}\ \frac{1}{4}h}$.
This can be expressed as $0.75h$, where $h$ represents the original length of her hair.
