Question

Write a rule that expresses the number of quarts q of a liquid as a function of the number of pints p.

Answer 1

1q = 2p

Explanation:

One quart of liquid is the equivalent of 2 pints... one of the rare easy measures in the American measure system.

So, the equation needs to have 1 quart on one side, and 2 pints on the other side. It's an equation because both values are equal, just expressed in different units.

1 quart = 2 pints, then rewritten to match the variables given in the question:

1q = 2p
