Answer:
72 guests
Step-by-step explanation:
We can add up the numbers of bottles per guest, then use that total to find the number of guests from the number of bottles.
<h3>Setup</h3>
Let g represent the number of guests at the party. Then there are ...
- g/3 bottles of coke
- g/6 bottles of sprite
- g/4 bottles of lift
The total number of bottles is ...
g(1/3 +1/6 +1/4) = 54
<h3>Solution</h3>
Multiplying by the inverse of the coefficient of g, we find its value to be ...
g(4/12 +2/12 +3/12) = g(9/12) = 54
g = 54(12/9) = 72
There are 72 guests at the party.
