Rafael in making punch and needs a gallon of raspberry and 2 liters of lemon-lime soda to make 12 cups. He pays &3.00 for a 2-liters container of lemon-lime soda and $4.00 for a quart of sober . What is the minimum amount he should charge per cup of punch to make a $10 profit
To make 12 cups of punch, Rafael needs 1 gallon, which is equal to 4 quarts, of raspberry.
For the 12 cups of punch, he needs 1 gallon + 2 liters = 4 quarts + 2 liters = 6 quarts of raspberry and lemon-lime soda.
Thus, he needs 6 quarts x $4/quart = $<<6*4=24>>24 for the raspberry.
Since 1 liter is equal to 1.06 quarts, then 2 liters is equal to 2 x 1.06 = 2.12 quarts.
Hence, Rafael needs a total of 6 quarts + 2.12 quarts = 8.12 quarts of raspberry and lemon-lime soda.
Therefore, he needs 8.12 quarts / 12 cups = 0.68 quarts per cup.
So, Rafael needs to have 0.68 quarts x $4/quart = $<<0.68*4=2.72>>2.72 for the raspberry and lemon-lime soda per cup.
Thus, the minimum amount he should charge per cup of punch to make a $10 profit is $10 + $2.72 = $<<10+2.72=12.72>>12.72. Answer: \boxed{12.72}.
