First find the number of quarts the hot tub holds by multiplying the number of gallons it holds by 4: 40 gallons * 4 quarts / gallon = 160 quarts. Then multiply the number of quarts of champagne Jackson buy by the normal price per bottle to find the cost before the discount: 160 quarts * $50 / quart = $8000. Then multiply that number by 20% to find the amount of the discount: $8000 * .2 = $1600. Finally, subtract the discount from the total cost to find the final amount Jackson pays: $8000 - $1600 = $6400.
The answer: 6400
Reverse engineering the question: Jackson wants to impress his girlfriend by filling her hot tub with champagne. The hot tub holds 40 gallons of liquid. Each bottle of champagne holds 1 quart. (There are 4 quarts per gallon). If each bottle of champagne costs $50, but Jackson gets a 20% volume discount, how much does he spend on champagne?
