Step-by-step explanation:
The fruit punch has 2.4 gallons but x %
Apple juice has 5.6 gallons but 100 % or 1
The total mixture would then have 8 gallons and 82 %.
2.4+5.6=8
8×0.82 = 6.56
Then you would do 2.4x + 5.6(1) = 6.56
2.4x + 5.6 = 6.56
2.4x = 0.96
0.96/2.4 = 0.4 = 40%
Therefore, Brand A has 40% fruit juice
