In order to facilitate people's travel, a supermarket launched the "Travel Convenience Package" for sale during the "Eleventh Golden Week". One pack: 2 sausages and 4 breads.

Group A sells Group A, Group B sells Group B and Group C sells Group C.. The sales amount of a set is 2×2+4× 1.2=8.8 yuan, and the sales amount of b set is 3× 2+8× 1.2+ 1×. According to the meaning of the question:

8.8a+25.6 b+2 1.2c = 44 1.24 a+6 b+4c = 1 16，

From the second equation: a= 1 16? 6b？ 4c4, substitute into the first equation:

12.4(b+c)= 186, namely b+c =15;

Then the sales amount of fruit juice =10 (b+c) =10×15 =150 (yuan).

Answer: Fruit juice sales 150 yuan.

So the answer is: 150.
