Explanation:
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
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 us represents number of people in the club by n
The the ounces of milk = m
The number of cookies = c
Jada's budget in dollars = d
y = 12(15)
She is preparing 4 cookies per person
4n = c
Since A package of cookies contains 24 cookies
She needs = 15 × 4 = 60 cookies
60 ÷ 24 = 2.5
Hence, approximately, she has to buy 3 packages of cookies
She needs = 15 × 12 = 180 ounces of milk
A 1-gallon jug of milk contains 128 ounces
180 ÷ 128 = 1.406
She needs to buy 2 A 1-gallon jug of milk
Note that: from the question
The cost of each jug of milk is $3
The cost of each package of cookies is $4.50
b represents Jada's budget in dollars
b = 2(3) + 3(4.50)
The equations that could represent the quantities and constraints in this situation are:
Options a, c and e are correct
