Question

Sandra wants to give a party for 60 people. She has a punch recipe that makes 2 gallons of punch and serves 15 people. How many gallons of punch should she make for her party?

Answer 1

Answer:

8 gallons

Step-by-step explanation:

#1: Set up a ratio from the recipe: gallons of punch to the number of people.

2 gallons 15 people

#2: Set up a ratio of gallons to the people coming to the party.

(Place the gallons on top) x gallons 60 people

#3: Set up a proportion 2 gallons       x gallons

                                       15 people  =    60 people

* Like units should be across from each other

4) Solve using the "lonely mate" formula

2 gallons           x gallons

15 people  =     60 people

2 x 60 = 120

120/15 = 8

This means she should make 8 gallons.
