Amy needs to purchase pencils and notebooks for her students. The number of pencils needed is at least twice as many as the number of notebooks. The pencils cost $0.25 each and the notebooks cost $4. Amy’s budget for these supplies allows for a maximum cost of $100. How do you represent the constraints of this scenario as a system of inequalities, where p is the number of pencils and n is the number of notebooks Amy will buy?(1 point)

p less than 2 n 0.25 p plus 4 n less-than-or-equal-to 100

p≥2n

0.25p+4n≤100

Answer 1

To represent the constraints of Amy's purchasing scenario as a system of inequalities, we can analyze the conditions given:

1. The number of pencils needed is at least twice as many as the number of notebooks. This translates to the inequality: \[ p \geq 2n \]

2. The maximum cost of the pencils and notebooks is $100. The cost of pencils is $0.25 each and notebooks are $4 each, which can be represented by the inequality: \[ 0.25p + 4n \leq 100 \]

Combining these two inequalities, the correct representation of the constraints is:

• \( p \geq 2n \)
• \( 0.25p + 4n \leq 100 \)

Therefore, the correct response is: p≥2n 0.25p+4n≤100
