Jada plans to serve milk and healthy cookies for a book club meeting. She is preparing 12 ounces of milk and 4 cookies per person. Including herself, there are 15 people in the club. A package of cookies contains 24 cookies and costs $4.50. A 1-gallon jug of milk contains 128 ounces and costs $3. Let $n$   represent number of people in the club,  $m$  represent the ounces of milk, $c$   represent the
number of cookies, and $b$   represent Jada's budget in dollars. Select all of the equations that could represent the quantities and constraints in this situation.

•  $m=12\left(15\right)$  

•  $3m+4.5c=b$  

•  $4n=c$  

•  $4\left(4.50\right)=c$  

•  $b=2\left(3\right)+3\left(4.50\right)$
