Using 2 Equations:
Quantity::: t + f = 15 liters
Juice:::0.20t + 0.05f = 0.16*15 liters
-------------------------------------
Multiply thru the 1st eq. by 5
Multiply thru the 2nd eq. by 100
----------
5t + 5f = 5*15
20t + 5f = 16*15
-------------------------------
Subtract and solve for "t":
15t = 11*15
t = 11 liters (amt. of 20% juice needed)
---
Solve for "f":
t + f = 15
11 +f = 15
f = 4 liters (amt. of 5 % juice needed)

.
Let x = amount (liters) of 20% OJ
then
15-x = amount (liters) of 5% OJ
.
.20x + .05(15-x) = .16(15)
.20x + .75 - .05x = 2.4
.15x + .75 = 2.4
.15x = 1.65
x = 11 liters (20% OJ)
.
5% OJ:
15-x = 15-11 = 4 liters
