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)

To represent the constraints of Amy's purchasing scenario as a system of inequalities, we need to derive the inequalities based on the information given:

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

  2. The total cost of the pencils and notebooks must not exceed Amy's budget of $100. The cost for pencils is $0.25 each and notebooks are $4 each. Thus, this constraint can be expressed as: \[ 0.25p + 4n \leq 100 \]

Therefore, the system of inequalities that represents the constraints is: \[ \begin{cases} p \geq 2n \ 0.25p + 4n \leq 100 \end{cases} \]

This corresponds to the response:

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

So the correct selection is:

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