Question

An acrylic container holding 1.5 gallons can only hold a liquid with a maximum of 7% alcohol content otherwise the container will become scratched. Wishing to make sangria you must use two bottles of wine (25 ounces each) at 11% alcohol. How much seltzer water should you add to bring the sangria to the 7% threshold? How much sangria have you made? Can you make a double batch in the container?

Answer 1

11% alcohol is 89% water

7% alcohol is 93 % water

 

0.89(50) + x = 0.93(50 + x)

 

Can you solve for x and answer?
