Answer:
At the end of the party <u>5.5 gallons or 88 cups</u> of punch will be leftover.
Step-by-step explanation:
Given:
There are 20 guest at a party.
Now, to find the quantity of punch that will be leftover.
Number of guests = 20.
Total gallons of punch = 8.
Now, using conversion factor we change gallons into cups:
1 gallon = 16 cup.
So, 8 gallons = 16 × 8 = 128 cups.
<u><em>Thus, total cups of punch = 128.</em></u>
Total number of cups each guest will drink = 2.
Now, to get total number of cups the 20 guests will drink by multiplying:
![20\times 2](https://tex.z-dn.net/?f=20%5Ctimes%202)
![=40\ cups.](https://tex.z-dn.net/?f=%3D40%5C%20cups.)
<u><em>Total number of cups the 20 guests will drink = 40.</em></u>
So, to get the leftover punch we subtract the total number of cups the 20 guests will drink from total cups of punch:
![128-40\\\\=88\ cups.](https://tex.z-dn.net/?f=128-40%5C%5C%5C%5C%3D88%5C%20cups.)
So, 88 cups = ![88\div 16=5.5\ gallons.](https://tex.z-dn.net/?f=88%5Cdiv%2016%3D5.5%5C%20gallons.)
Therefore, at the end of the party 5.5 gallons or 88 cups of punch will be leftover.
