Pete starts with 4 quarts of 20% juice, which contains
0.20 • (4 quarts) = 0.8 quarts
of juice.
If he mixes this with <em>x</em> quarts of 60% juice, which contains
0.60 • (<em>x</em> quarts) = 0.6<em>x</em> quarts
of juice, then he would end up with a mixture with a volume of (<em>x</em> + 4) quarts that contains (0.8 + 0.6<em>x</em>) quarts of juice. The mix has to have a concentration of 50% juice, which means
(0.8 + 0.6<em>x</em>) / (<em>x</em> + 4) = 0.50
Solve for <em>x</em> :
0.8 + 0.6<em>x</em> = 0.50 (<em>x</em> + 4)
0.8 + 0.6<em>x</em> = 0.5<em>x</em> + 2
0.1<em>x</em> = 1.2
<em>x</em> = 12
So Pete needs 12 quarts of the 60% juice.

Step-by-step explanation:
9 * x < ( with the line under it) 48
Answer:−
3c+2
Step-by-step explanation:
A) Business means the process of earning money, so she earned $350 at first time, so her initial value would be: $350
Rate of change = 750 - 350 / 350 * 100
= 400 / 350 * 100
= 40000 / 350
= 114.28
Now, There are 4 years between 2014 & 2010 so it will be:
= 114.28 / 4 = 28.57
In short, Your Answer would be 28.57% per year
B) Equation would be: Y = x + 0.2857x
Where, x = number of year
Hope this helps!
