8. During the lunch break on the day of the "13th Element. ALchemy of the Future" competition, a cafeteria worker mixed 2 liters of one juice with a $10 \%$ sugar content and 3 liters of another juice with a $15 \%$ sugar content. What is the sugar content of the resulting mixture?
a) $5 \%$

б) $12.5 \%$

в) $12.75 \%$

г) $13 \%$

д) $25 \%$
8. Answer g. In the first juice, there is $0.1 \cdot 2=0.2$ liters of sugar, and in the second juice, there is $0.15 \cdot 3=0.45$ liters of sugar. Then, in the resulting mixture, there will be $0.2+0.45=0.65$ liters of sugar. The total volume is 5 liters. Then the percentage of sugar in the mixture is $\frac{0.65}{5} \cdot 100 \% = 13 \%$.
