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:
<span>y= -2/3 - 5x
or
</span>y= -5x -2/3
so
slope = -5
we are given
Since, we have to solve for x
so, we will isolate all terms on left side
step-1:
Distribute -2x
step-2:
Add both sides by 2x
Step-3:
Divide both sides by -2
and we get
now, we can take sqrt both sides
we get
