What system of inequalities would you use to solve the problem below?

You must buy cupcakes and pizza for a party. Each cupcake costs [tex]$3, and each pizza pie costs $[/tex]12. You know that you need at least 5 pizzas so that each person can have at least 2 slices of pizza. In addition, you cannot spend more than $100. If you want to figure out how many cupcakes and pizza pies you can buy, what system of inequalities would you write?

A. [tex]\begin{array}{l}c + p \leq 100 \\ 3c + 12p \geq 5\end{array}[/tex]

B. [tex]3c + 12p \ \textgreater \ 100 \, \, p \ \textless \ 5[/tex]

C. [tex]3c + 12p \ \textless \ 100 \, \, p \geq 2[/tex]



Answer :

To determine how many cupcakes and pizza pies you can buy given the constraints of the problem, we will formulate a system of inequalities.

Let's denote:
- [tex]\( c \)[/tex] as the number of cupcakes,
- [tex]\( p \)[/tex] as the number of pizza pies.

The constraints given in the problem are:
1. Each pizza pie costs [tex]$12, and you need at least 5 pizza pies. This can be written as: \[ p \geq 5 \] 2. Each cupcake costs \$[/tex]3.

3. You cannot spend more than \[tex]$100 in total. The total cost of cupcakes and pizza pies should not exceed $[/tex]100. This can be written as:
[tex]\[ 3c + 12p \leq 100 \][/tex]

Therefore, the system of inequalities that represents this situation is:
[tex]\[ \begin{array}{l} p \geq 5 \\ 3c + 12p \leq 100 \end{array} \][/tex]

Among the given options, the one that matches our system of inequalities is:
D. [tex]\( p \geq 5, 3c + 12p \leq 100 \)[/tex]

So, the correct answer is:
D. [tex]\( p \geq 5, 3c + 12p \leq 100 \)[/tex]
