Answer:
11 L of 20% juice and 4 L of 5% juice
Step-by-step explanation:
Let
x L = amount of 20% juice
y L = amount of 5% juice
<u>20% juice:</u>
Amount = x L
Amount of juice
L
<u>5% juice:</u>
Amount = y L
Amount of juice
L
<u>16% juice:</u>
Amount = 15 L
Amount of juice
L
We mixed x L of 20% juice with y L of 5% juice to get 15 L of 16% juice, so

and

From the first equation:

Substitute it into the second equation:

Answer:
equation will be 2439+/=w
Step-by-step explanation:
It is pretty clear from the question, that
the weight of the load is /. and the weight of the empty truck is 2439 pounds.
It means when we load the truck with '/' pounds load, trucks weight increases and is given by
w = 2439 + /
For Example:
Suppose if load / = 1000 pounds it means weight of the truck after adding the load will be
w=2439+1000=3439 pounds.
