Sagot :
One gallon equals to 4 quarts.
The instructions tell you to add 1 part of cleaner and 3 parts of water, in total 4 parts. It makes it easy as you can take that one part = one quart.
You will use 3 quarts of water and 1 quart of cleaner. The answer is D.

let
x--------> gallons of cleaner
y-------> gallons of water
we know that
[tex]x+y=1[/tex] equation 1
and
[tex] \frac{x}{y} = \frac{1}{3} \\ y=3x [/tex] equation 2
substitute equation 2 in equation 1
[tex]x+3x=1 \\ 4x=1 \\ x=1/4 gal[/tex]
find the value of y
[tex]y=3x \\ y=3* \frac{1}{4} \\ y= \frac{3}{4} gal[/tex]
we know that
[tex] \frac{1}{4} gal[/tex] is equal to [tex]1 quart[/tex]
therefore
the answer is the option
D) 1 quart
