Select the correct answer.

Susan is planting marigolds and impatiens in her garden. Each marigold costs [tex]$\$[/tex] 9[tex]$, and each impatien costs $[/tex]\[tex]$ 7$[/tex]. Susan wants the number of marigolds to be more than twice the number of impatiens. She has a maximum of [tex]$\$[/tex] 125$ to spend on the plants. This situation can be modeled by this system of inequalities.

[tex]\[
\begin{aligned}
9x + 7y & \leq 125 \\
x & \ \textgreater \ 2y
\end{aligned}
\][/tex]

Which statement describes the system of inequalities?

A. The system represents the minimum amount that Susan can spend on marigolds, [tex]$x$[/tex], and impatiens, [tex]$y$[/tex], and the relationship between the number of marigolds and impatiens.

B. The system represents the maximum amount that Susan can spend on marigolds, [tex]$x$[/tex], and impatiens, [tex]$y$[/tex], and the relationship between the number of marigolds and impatiens.

C. The system represents the maximum amount that Susan can spend on impatiens, [tex]$x$[/tex], and marigolds, [tex]$y$[/tex], and the relationship between the number of marigolds and impatiens.

D. The system represents the minimum amount that Susan can spend on impatiens, [tex]$x$[/tex], and marigolds, [tex]$y$[/tex], and the relationship between the number of impatiens and marigolds.


Sagot :

Let's break down the given system of inequalities:

1. \( 9x + 7y \leq 125 \):
- This inequality represents the constraint on the total cost of the marigolds (denoted by \( x \)) and impatiens (denoted by \( y \)). Each marigold costs \( \[tex]$9 \) and each impatien costs \( \$[/tex]7 \). The total amount Susan can spend on these plants should not exceed \( \$125 \).

2. \( x > 2y \):
- This inequality represents the relationship between the number of marigolds (\( x \)) and the number of impatiens (\( y \)). Specifically, the number of marigolds should be more than twice the number of impatiens.

The correct statement needs to encapsulate these interpretations:

- \( 9x + 7y \leq 125 \) describes the maximum amount Susan can spend on marigolds and impatiens.
- \( x > 2y \) describes the relationship that the number of marigolds should be more than twice the number of impatiens.

Therefore, comparing all the given options:

A. This statement mentions the minimum amount spent, which is incorrect because the inequality indicates a maximum spending limit.

B. This statement correctly identifies the system of inequalities as representing the maximum amount that Susan can spend on marigolds (\( x \)) and impatiens (\( y \)), and correctly describes the relationship between the number of marigolds and impatiens.

C. This statement switches the variables \( x \) and \( y \), incorrectly identifying impatiens as \( x \) and marigolds as \( y \).

D. This statement incorrectly describes the inequalities in terms of minimum spending.

The correct answer is:
B. The system represents the maximum amount that Susan can spend on marigolds, [tex]\( x \)[/tex], and impatiens, [tex]\( y \)[/tex], and the relationship between the number of marigolds and impatiens.
