Question

If I have an equation in which x = pounds, and y = total cost, can I substitute quarts into the equation

Answer 1

Yes, you can

Explanation:

As a point of reference, assume the equation is:

`y = 5x`

Where

`y = total\ cost`

and

`x = pounds`

In standard unit of conversion:

`1\ pound = 0.4793\ quart`

So:

`x\ pounds = 0.4793x\ quart`

Substitute 0.4793x for x in
`y = 5x`

`y = 5 * 0.4793x`

`y = 2.3965x`

The above equation is the equivalent of
`y = 5x` in quarts

So, irrespective of what the equation is, you can always substitute quarts into the equation.
