how many quarts of antifreeze are in the resulting mixture?

Question

Suppose 6 quarts of a solution that is 52% antifreeze is mixed with 10 quarts of a solution that is 32% antifreeze.

Answer 1

Just find how much antifreeze is in each mixture and add them together!

 

6(.52) = 3.12 quarts in the first mixture

10(.32) = 3.2 quarts in the second mixture

 

3.12 + 3.2 = 6.32 quarts of antifreeze in the resulting mixture
