Alligation Word Problem
by Josie
A nurse has a 70% alcohol solution and a 30% alcohol solution. How many mL of each should be used to make 400 mL of a 40% alcohol solution? This is a good alligation practice problem. Remember that as soon as you see there is a higher and a lower strength to work with, start thinking about writing out a tic-tac-toe grid and running an alligation. |
