You use preterite to describe an action that took place and was fully done, Ex. José entro a la habitación, you can see John went into the room, he completed the action. On the other hand, imperfect tense doesn't specificate if the action was completed, Ex. José entraba a la habitación, it doesn't tell us if José fully entered the room.
This situation of the recipe can be represented as y=x+5.5 and it is expected that x is ≥ 0 and y is ≥ 5.5.
<h3 /><h3>What is the equation for this situation?</h3>
It is known the total amount of flour (y) is equivalent to the total amount of whole wheat flour (5.5) added to the total white flour (x). Therefore, the equation is:
<h3>What are the possible values?</h3>
- x = It is expected x is equalthan 0 or greater to it since the minimum amount of white flour that can be added is 0.
- y = It is expected y is equal than 5.5 or greater to it since even if no white flour is added the minimum total is 5.5.
