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(15)

3 m + 4.5 c=b

4n = c

B= 2 (3) + 3 (4.50)

4 (4.50) = c
