What percentage of the resulting mixture is antifreeze

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

The final solution will contain 16 quarts because 6 quarts are being combined with 10 quarts.

The 6 quart solution contains 0.52(6) quarts of antifreeze, or 3.12 quarts.

The 10 quart solution contains 0.32(10) quarts of antifreeze, or 3.2 quarts.

So the final solution contains 3.12 + 3.2 = 6.32 quarts of antifreeze.

Answer the question:

6.32 is what percent of 16?

6.32 = x% (16)

x% = 6.32/16 = 0.395 (or as a percentage 39.5%)
