If I have an equation in which x = pounds, and y = total cost, can I substitute quarts into the equation
Colt1911 [192]

Answer:

Yes, you can

Step-by-step 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

<em>So, irrespective of what the equation is, you can always substitute quarts into the equation.</em>
