Question

At a New Year’s party, Brian’s guests drank 3 liters of club soda, 7 liters of cola, 5 liters of punch, 6 liters of fruit juice, 5 liters of seltzer, and 6 liters of ginger ale. There were 40 guests at the party. On average, how many liters of beverages did each person consume?

Answer 1

3+7+5+6+5+6=32

THERE WERE 40 GUESTS

SO 40/32=1.25

ANSWER=1.25

Answer 2

To find the average number of liters that each person consumed, let us first find out how many liters were consumed in total. Add up all of the liters:

3 + 7 + 5 + 6 + 5 + 6 = 32 liters

There were 40 guests at the party, so in order to find out the average amount that each person consumed, we must divide the number of liters by the number of people at the party:

$\frac{32}{40}= \frac{16}{20}= \frac{8}{10}= \frac{4}{5}$

This means that on average, each person consumed $\frac{4}{5}$ of a liter of beverage.
