Write an inequality in standard form that models the following statement:

The difference of [tex]x[/tex] and [tex]5y[/tex] is fewer than 83.

A. [tex]x - 5y \ \textgreater \ 83[/tex]
B. [tex]5y \geq -x + 83[/tex]
C. [tex]x - 5y \ \textless \ 83[/tex]
D. [tex]5y \leq -x + 83[/tex]

Answer :

To solve the problem, we need to translate the given statement into a mathematical inequality. The statement is: "The difference of [tex]\( x \)[/tex] and [tex]\( 5y \)[/tex] is fewer than 83."

Here's how we can interpret and solve this:

1. Identify the Mathematical Expression:
- The phrase "the difference of [tex]\( x \)[/tex] and [tex]\( 5y \)[/tex]" refers to subtracting [tex]\( 5y \)[/tex] from [tex]\( x \)[/tex], which is expressed as [tex]\( x - 5y \)[/tex].

2. Translating the Phrase "Fewer Than":
- The words "fewer than" indicate a strict inequality "<" (less than).

3. Construct the Inequality:
- Combining the expression and the inequality, we get:
[tex]\[
x - 5y < 83
\][/tex]

4. Select the Correct Answer:
- We compare this inequality with the given options:
- [tex]\( x - 5y > 83 \)[/tex]
- [tex]\( 5y \geq -x + 83 \)[/tex]
- [tex]\( x - 5y < 83 \)[/tex]
- [tex]\( 5y \leq -x + 83 \)[/tex]

- Clearly, the option [tex]\( x - 5y < 83 \)[/tex] matches our translated inequality.

Therefore, the correct inequality that models the statement is [tex]\( x - 5y < 83 \)[/tex].
