Chin canned a number of quart jars and a number of pint jars of tomato. She canned total of 40 quarts, now what equation model did Chin used in the scenario

let’s simplify the problem:
Pint = 16oz
quart = 32oz

what model best show to get 40quarts.
=> p + q = 40
=> 16p + 32q = 40

the equation model that Chin used to get 40 quarts is p + q.
