Alex knits hats and scarves to sell at an art fair. He can make no more than 40 items altogether in time for the art fair. Write and graph a system of inequalities that shows the possible numbers of hats and scarves Alex can bring to the art fair if he wants to bring at least 25 items.

Let [tex]x[/tex] represent the number of hats that Alex makes, and let [tex]y[/tex] represent the number of scarves that Alex makes.

Identify the inequalities in the system of inequalities that shows the possible numbers of hats and scarves Alex can bring to the art fair if he wants to bring at least 25 items. Select all that apply.

A. [tex]x+y \leq 25[/tex]

B. [tex]x-y \leq 40[/tex]

C. [tex]x-y \leq 25[/tex]

D. [tex]x+y \geq 40[/tex]

E. [tex]x-y \geq 25[/tex]

F. [tex]x-y \geq 40[/tex]

G. [tex]x+y \geq 25[/tex]

H. [tex]x+y \leq 40[/tex]

Answer :

To solve the given problem, we need to determine the possible numbers of hats and scarves Alex can bring to the art fair, given the constraints provided. Let's walk through the steps:

1. Identify Variables:
- Let [tex]\( x \)[/tex] represent the number of hats Alex makes.
- Let [tex]\( y \)[/tex] represent the number of scarves Alex makes.

2. Determine Constraints:
- Alex can make no more than 40 items in total. This gives us the inequality:
[tex]\[
x + y \leq 40
\][/tex]
- Alex wants to bring at least 25 items total. This gives us another inequality:
[tex]\[
x + y \geq 25
\][/tex]

3. Formulate the System of Inequalities:
- The system of inequalities that represents Alex’s conditions is:
[tex]\[
\begin{cases}
x + y \leq 40 \\
x + y \geq 25
\end{cases}
\][/tex]

4. Analyze the Choices:
- From the options provided, we need to select the inequalities that match our system:
- Choice G: [tex]\( x + y \geq 25 \)[/tex]
- Choice H: [tex]\( x + y \leq 40 \)[/tex]

By following these steps, we conclude that Alex's possible numbers of hats and scarves are described by the inequalities [tex]\( x + y \geq 25 \)[/tex] and [tex]\( x + y \leq 40 \)[/tex]. Therefore, the correct answers are choices G and H.
