Jackson and derek have a lemonade stand. they sell lemonade in 12oz cups. they are hoping to sell at least 50 cups of lemonade. jackson says that they should make 5 gallons, but derek thinks that 17 quarts of lemonade will be enough. whose amount will give them enough lemonade to fill 50 12oz cups ?

Hello mate!

here we know that in each cup there is 12 oz, and they expect to sell 50 cups, then they expect to sell 50*12oz = 600 oz in a total of lemonade.

Jackson says that they should make 5 gallons, and Derek thinks that 17 quarts are enough, first write this quantity as oz and see which one is right.

1 gallon is equal to 128 oz, then 5 gallons are equivalent to 5*128oz = 640 oz, so in this situation the have more than enough.

1 quart is equivalent to 32 oz, then 17 quarts are equivalent to 17*32oz = 544 oz, which is less than the amount needed in order to sell 50 cups.

Then the correct amount is 5 gallons.
