For this item, we may let x be the number or liters of apple juice present in the ginger ale. The total volume of the punch then becomes
total volume = 2 + x
Then, considering that 75% of this is apple juice,
x/(2 + x) = 0.75
x = 0.75(2 + x) = 1.5 + 0.75x
x = 1.5 + 0.75x
Also, for this item, the vaue of x is equal to 6 liters.
The answer is (1/3). So first you need to determine the fraction of time the second person worked. Multiply (1/2)x(1/3) and you will get (1/6). All the values need to add up to 1, so you can make the equation (1/2)+(1/6)+x=1. Solve for x and you will get (1/3).
The best and most correct answer among the choices provided by your question is the second choice or letter B "20".
The current area is 120(80)=9600 and he want to expand it by 4400 so that the new area will be 9600+4400=14000
14000=(120+x)(80+x)
14000=9600+200x+x^2
x^2+200x-4400=0
x^2-20x+220x-4400=0
x(x-20)+220(x-20)=0
(x+220)(x-20)=0, since x is an increase it must be greater than zero so
x=20ft
(120+20)(80+20)=14000ft^2
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
