Answer:
Yes, you can
Step-by-step explanation:
As a point of reference, assume the equation is:
[tex]y = 5x[/tex]
Where
[tex]y = total\ cost[/tex]
and
[tex]x = pounds[/tex]
In standard unit of conversion:
[tex]1\ pound = 0.4793\ quart[/tex]
So:
[tex]x\ pounds = 0.4793x\ quart[/tex]
Substitute 0.4793x for x in [tex]y = 5x[/tex]
[tex]y = 5 * 0.4793x[/tex]
[tex]y = 2.3965x[/tex]
The above equation is the equivalent of [tex]y = 5x[/tex] in quarts
So, irrespective of what the equation is, you can always substitute quarts into the equation.
