GuDViN [60]

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

=40\ cups.

<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.

So, 88 cups = 88\div 16=5.5\ gallons.

Therefore, at the end of the party 5.5 gallons or 88 cups of punch will be leftover.
