Explanation:
This can be solved through algebraic calculation:

Let
#x# the volume of#80% sugar solution# 
Let
#17.1x# the volume of#50% sugar solution# 
The desired mixture is
#60% of 17.1 fl.oz sugar solution# 
Write down the algebraic equation as:
#0.80(x) + 0.50(17.1x)(0.50) = 0.60(17.1)# 
Do the algebraic calculation to find the value of
#x# 
#x=5.7# for#80% sugar solution# 
Therefore, to find the other volume; subtract
#x=5.7# from#17.1x# ; to get#11.4 fl. oz. 50% sugar solution# .
