B and F , wish you the best enjoy!
Cross multiply and set it up like this.
1800 X

80 24
Multiply 1800•24
Then divide by 80 and you get 540.
8 gallons= 128 cups
20 guests x 2 cups each= 40 cups will be gone
128-40= 88 cups left over
88 cups= 5.5 gallons of punch left at the end of the party.
X + 18 = 5x - 38
x - x + 18 = 5x - x - 38
18 = 4x - 38
18 + 38 = 4x - 38 + 38
56 = 4x
56/4 = 4x/4
14 = x
