The volume of premium antifreeze to be used is 60 gallons.
The volume of water to be used is 120 gallons
<h3>What is a percentage?</h3>
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Let the volume of 60% pure antifreeze be used to make 20% pure antifreeze.
= x gallons
The volume of 20% pure antifreeze = 180 gallons
For 60% pure antifreeze:
C₁ = 60% , V₁ = x gallons
For 20% pure antifreeze :
C₂ = 20% , V₂ = 180 gallons
Applying,
C₁V₁ = C₂V₂
60 × x = 20 × 180
x = 60 gallons
The volume of 60% pure antifreeze used = 60 gallons.
The volume of water to be used.
= 180 - 60 gallons
= 120 gallons
Thus,
The volume of premium antifreeze to be used is 60 gallons.
The volume of water to be used is 120 gallons

Is it a written response or a multiple chose question?
Answer:
Red color= 28 balloon
Blue color= 14 balloon
White color= 7 balloon
Step-by-step explanation:
Given: There are 49 balloons
As given, there are 2 red balloon equal to the number of blue balloon
∴ 
Again given, there are 1/2 white balloon equal to the number of blue balloon.
∴ 
As above equation, we can understand that:
multiplying both side by 2
⇒ 
which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.
∴ Total combination of all color of balloon= 
Now, checking how many number of times combination can we have in 49 balloon.
Next, finding number of balloon in each color.
Red color= 
Blues color= 
White color=
