How would you follow up on this post on this to give it meaning and not be a warm fuzzy discussion post?

Describe why each variable is either discrete or continuous: Paint cans sold and paint used to cover walls. Answer- Paints cans sold is a discrete data, a data value or variable obtained from counting all the data set or sold cans. All variables of a discrete function are countable. Paint used to cover walls is continuous data, a data value or variable obtained by measuring all the data set. In other words, the variables of a continuous function take a long time or forever to count. We measure paint in liters.
