P=percentage of combined solution.
.
Find the amount of alcohol in each solution:
0.02(17.5)+0.05(8.25)=P(25.75)
.
Add to find total alcohol in combined solutions:
0.35+0.4125=P(25.75)
.
Divide by total alcohol by total amount of solution to find percentage:
0.7625/25.75=P
0.03=P
.
ANSWER: The combined solution is 3% alcohol.
