1.the class is having a valentine party. each student will get an 8-oz. cup of pepsi. how many 64-oz. bottles must be bought for a class of 30 students?

3.75 ≈ 4 bottles

Step-by-step explanation:

Each student consumes 8 ounces of Pepsi.

Each bottle contains 64 ounces.

There are 30 students.

* The first thing we must do is find the total consumption "c" of refreshment of the 30 students. To do this, we perform the following operation:

c = 30(8)

c = 240 oz.

A total of 240 oz of Pepsi will be needed.

* Based on the previous result, we want to know how many 64-ounce Pepsi bottles we should buy. Then we divide:

You can not buy 3.75 bottles. Therefore we round this amount to 4.

They should buy 4 bottles of Pepsi.
