Question

there are 20 guests at a party the host has 8 gallons of punch he estimates that each guess within 2 cups of punch if his estimate is correct how much punch will be left over at the end of the party

Answer 1

STEP 1:
convert gallons to cups & calculate total number of cups

1 gallon= 16 cups

= 8 gallons * 16 cups/gallon
= 128 cups total


STEP 2:
calculate total cups estimated for 20 guests

= 20 guests * 2 cups/guest
= 40 cups needed for guests


STEP 3:
subtract the difference between step 1 and step 2 to find leftover punch

= 128 cups - 40 cups
= 88 cups leftover

OR

GALLONS LEFTOVER
= 88 ÷ 16 cups/gallon= 5 1/2 gallons


ANSWER: There will be 88 cups or 5 1/2 gallons of punch leftover.

Hope this helps! :)
