Answer:

6 liters

Step-by-step explanation:

Let x represent the amount of pure concentrate used to make the punch. Then the total amount of concentrate in the punch is ...

0.20·10 +1.00x = 0.50(10+x)

x +2 = 0.5x +5 . . . . . eliminate parentheses

0.5x = 3 . . . . . . . . . . .subtract 2+0.5x

x = 6 . . . . . . . . . . . . . multiply by 2

6 liters of pure concentrate must be added to make a 50% punch.
