The answer is watchfulness
Your questions is not so clear, but I will try to answer it as I understand it.
I am a native Spanish speaker so you can trust my answer, if there is a problem with it, it is due the missing information in the question, but I think we can work it out for the best.
In Spanish when you want to make any negative setence in any tense we do not use an auxliliary verb as you do in English, we simply add the word:
No before the verb, for example in:
Yo no <u>quería</u> bailar en la fiesta. (I didn´t <u>wan</u>t to dance at the party)
Mi hermana no <u>piensa</u> antes de hablar. (My sister doesn't <u>think</u> before talking)
No me <u>hables</u>, no <u>quiero</u> nada. (Don't <u>talk</u> to me, I <u>want</u> nothing)
In Spanish we Simply use the Negative Adverb:
No
The opportunity cost of going to a night party instead of babysitting at home is:
- The benefit of taking care of the baby adequately and completing your work that you would have gained from babysitting that night.
<h3>What is an opportunity cost?</h3>
This is the loss of value or benefit that would have been incurred by engaging in an activity rather than engaging in an alternative activity.
The opportunity cost in this scenario is the value of what you gave up in other to attend the party, which was to babysit the child and take proper care of the baby.
In conclusion, an opportunity cost is the loss of other alternatives when one alternative is already chosen.
