Question 952253
Suppose 11 quarts of pure antifreeze is mixed with 5 quarts of a solution that is 16% antifreeze.
--------------------------------
 Answer the questions below. Do not do any rounding. 
(a) How many quarts of antifreeze are in the resulting mixture?
Equation:
Ans:: 11 + 0.16*5 = 11 + 0.8 = 11.8 quarts of antifreeze
 __11.8 quarts
====================
 (b) What percentage of the resulting mixture is antifreeze?
Total liquid:: 16 quarts
Total antifreeze:: 11.8
Percent antifreeze:: 11.8/16 = 0.7375 = 73.75%
